= BLAST PIT =

ALL MAPS:
* Cut down on supplies in general to make the chapter more challenging - the number of full heals was excessive, and given WGH and PU's status as "military strongpoints" (so to speak), BP having less ammo overall balances out nicely
- Bolstered enemy numbers in general, especially when it comes to bullsquids - melee-only squids aren't as aggressive as I'd once hoped

bm_c1a4a:

- Added the 357 to the player's spawn equipment
* Added shadows to the grate in the alternate vent pathway
* Made the EAS broadcast timing a bit tighter, so the player's less likely to miss it
* Added a pack of sleeping houndeyes at the bottom of the elevator
- Swapped a group of headcrabs on the track for a group of houndeyes as well
- Re-enabled pickup on the barrels in the pipe room, so they can be stacked and used as a shortcut
- Made the crate near said barrels not self-destruct when the player grabs it

bm_c1a4b:

- Added the 357 to the player's spawn equipment
- Re-added the hungry bullsquid near the start
- The catwalks outside the silo can now be destroyed again, as per HL1
* Partial fix for the desynced scientist/tentacle drag/eat animation
- Added some crates to the silo itself, as per HL1
* Fixed missing decal outside silo on way to oxy/fuel supply (there are probably more instances of this, though)
* Fixed clip brushes on fuel/oxy pipes in silo extending further down than the pipes themselves
* Fixed crate pieces on way to bm_c1a4d transition not being flagged as debris
* Fixed zombies on path to fuel/oxy area walking around instead of playing dead if the player turned on the generator first
* Fixed the bullsquid on the path to the generator blowing up the explosive barrels for no apparent reason

bm_c1a4c:

- Added the 357 to the player's spawn equipment
* Made the giant fan toggleable, to prevent softlocking if the player doesn't react quickly enough
* Fixed a glaringly obvious softlock - if the player drops down the elevator shaft again, the door to the fan is locked and won't open. The ladder down the elevator shaft now drops so the player can climb back up if they fall down again

bm_c1a4d:

- Added the 357 to the player's spawn equipment
- Restored the electrified water "puzzle" from HL1
* Added some detail to the lower hallway reminiscent of HL1

bm_c1a4e:

* Added a global state so the ironsights hint for the 357 won't appear if the player already has it
* Fixed some clipping issues with the "xen infestation" stuff at the beginning
* Added the "radioactive" effect around the waste in the "xen infestation" area

= POWER UP =

ALL MAPS:

* Changed up the zombie HECU scene a little bit
* Fixed trams sometimes not sounding like metal when hit
* Added missing rear lights to trams
* The guard should no longer warn the player about the Garg after it's killed
* Garg ambience should no longer play in the starting area after the Garg's death
* Removed some static padlocks

bm_c2a1b:
* Fixed exploding gas tanks not sounding like metal when shot
- Restored the marines using the ledges on either side of the main room (TODO: Investigate this)
- Added back some satchel charge pickups
* Fixed some silly houndeye visibility stuff
* Fixed a silly oversight where the player could jump back up the broken stairwell very easily, which could probably cause all sorts of bugs
* Added a few more houndeyes for flavour
* Added some crates as intuitive tripmine mounting spots near the elevator
* Replaced cheap old-style water around generator with Xen-style refractive prop
* Removed a clip brush that made the player stand off the floor in the water - this made the zombie look shorter than intended and didn't seem to serve any other purpose
* Cleaned up the blocked generator a bit so the crate isn't obtuse and indestructible until the player gets close enough (though it's still immune to houndeyes to prevent accidental sequence breaking)

= ON A RAIL =

ALL MAPS:
* item_crate/supply crate prop shenanigans - unsealed crates/lids are now prop_physics instead of item_crate and lids are now debris
* Fixed tram sometimes not sounding like metal when hit
* LIGHTING OVERHAUL - The entire chapter is now darker and colder, to bring it more in line with its HL1 incarnation
* Enemy placement has been rebalanced and increased a bit

- Restored old plug puzzle - platform in water, two buttons, etc.
- Restored vorts teleporting in when the player lowers the bridge
* Fixed tram always stopping at the bridge, even when it's lowered
* Replaced one of the stairwell barnacles with a zombie to prevent clipping issues
* Made turntable elevator collision actually sound like metal

bm_c2a2b:
* Added an extra sentry near the beginning
* Added/expanded a side area as a callback to HL1 and to encourage exploration
* Moved the tripmines above the track a bit

* Fixed NPCs running through the railings entirely
* Fixed the guard changing appearance when dying and turning his head to look at the player post-death, somehow
* Implemented improved death scene choreography, courtesy of Citizen⁵
* Attempted fix for some softlocks throughout the rocket silo

KNOWN BUGS:
* RAGDOLL-RELATED PERFORMANCE HITS. I've done what I can to try and eliminate the huge perf drop that happens in the silo sometimes, but I'm not sure it worked. Will investigate further.

bm_c2a2c:
* Fixed .50 cal "ambush" marines getting stuck in doors
* Fixed the starting chargers resetting to full charge on map transition
- Completely overhauled the launch pad fight to prevent cheesing - it now bears more resemblance to its 2012 iteration, but with 1.5's visuals and some of its additions. An overview:
-- Closed off the 1.0/1.5 entrance path in favour of the main gate opening
-- Removed the .50 cal in the launch control pad bunker, moved the other one to the far right corner - same effect, but with a clearer sightline to the marine on it
-- Cut down on supplies a bit and rearranged the ones that are left
-- Adjusted "wave" timing to try and make the fight line up with the music a bit better (though this is obviously very dependant on the player's actions so it's not perfect)
-- Removed some foliage on the launch pad to improve sightlines
* Removed one marine and added some extra cover/health kits to improve player guidance
* Attempted some optimization in the rocket silo - removing unseen/disabled lights, etc.
* Fixed some railing backfaces being visible outside the launch pad
* Fixed satchel charges nearby being unusable to the player
* Fixed exploding gas tank not sounding like metal when shot

* Rotated door status lights so they're "upright", as opposed to sideways
* Some changes to the Apprehension connection room, as a callback to HL1
* Fixed the Apprehension train not sounding like metal when hit
* Removed a static padlock
* Lowered the Apprehension train's max speed to try and mitigate clipping issues

KNOWN BUGS:
- Marines lose their weapons when they get off the .50 cal, and one guy seems dead-set on jumping on it near the end of the fight. I'm putting these down to BM limitations, I can't figure out what the hell's going on here.

= APPREHENSION =

ALL MAPS:
* Enemy placement/numbers and ammo/item pickups adjusted, as per usual
* Lighting adjustments - colder in some places, dimmer overall
* Crossbow ammo adjustment - I strongly recommend installing my Ammo Pickup Fix plugin, as the map's ammo placement has been designed with it in mind. Ammo counts will still (hopefully) be reasonably balanced without the plugin.

bm_c2a3b:
* Significant optimization pass
* Adjusted the broken walkways in the big ichthy room
* Big detail pass in the underwater sections - they now actually have some purpose to them!
- Restored ladder climbing up into piston room

- Allowed the player to open the cryo room door while the scientist is talking, a la HL1

bm_c2a3c:
* Significant optimization pass
- Put the blast door controls back in the office
* Adjusted the guard death scene to give the assassin a bit more cover when retreating
* Adjusted the layout of the assassin hangar, to give the assassins more verticality
* Some other layout adjustments to improve the combat flow in general
- Made the assassins drop their Glocks again, kinda

= RESIDUE PROCESSING =

bm_c2a4c:
- Moved music trigger forward a bit, hopefully should be timed a bit better now
- Opened up some of the conveyor belts again, to allow for exploration
- Broke the ladder in the conveyor crane room

* Fixed stoves in canteen not sounding like metal when hit
* Adjusted the end of the map to make it more sensible story-wise

bm_c2a4f:
* Fixed guard shooting at alien grunts from control room

* Attempted fix for scientists/guard getting stuck and softlocking the player after the surgery machine is turned off
* Fixed zombie visually spawning in if the player breaks the tarp crate before entering the normal spawn trigger
* Moved a gib in the autopsy room that was getting in the way of the off switch
* Added one of the Gonarch flame spout plants to the xen habitat room

= SURFACE TENSION =

ALL MAPS:
* Supply (health, batteries, ammo) and enemy placement has been adjusted
* Added Knockback Houndeyes from Xen chapters
* Swapped out almost all old-style AGrunts for Xen Grunts (some old AGrunts are still in use in some places where the Xen Grunts didn't work properly)

* Clipping pass - fixed a few rocks with particularly bad physics meshes here and there

bm_c2a5a:

- Restored the second minefield area with the Tentacle
* Added a few more frag grenades in the broken crate just before the minefield
* Fixed (ish) a bug where a headcrab in the minefield would be invisible
* Minor detailing around the storm drain hatch for better guidance

KNOWN BUGS:
* The tentacle *may* occasionally disappear entirely. I've done my best to work around this, but I doubt it's been eliminated entirely, and I don't think there's anything more I can do to improve it.

bm_c2a5c:
* Fixed alpha sorting issues with fake skybox fog and smoke from crashed helicopter
* Fixed rock material used on the cliffs - colour is now more consistent with the rock models and it's no longer shiny
* Adjusted animation speed of the bunker getting destroyed in the skybox
(Thanks to Citizen⁵ for inspiration/help on these)
* Attempted to improve NPC pathing on the cliffs - this seemed to be responsible for the majority of the assaults in the map not working correctly
* Made the RPG resupply crates refill 10 rockets at once, thus ensuring the player will have max ammo (unless they have an edited skill.cfg)

* Detailing/expansion in a few places outdoors
* Adjusted tripmine placement a bit to make them less obvious/more hazardous
* Adjusted sniper behaviour and positioning
* Cut down on the ridiculous number of explosives/tripmines inside the ordinance building, in an attempt to counteract a bug where tripmines wouldn't do damage
* Moved the Hivehand and AGrunt corpse down to the bottom of the elevator, so the player's more likely to hear the guard's reaction
* Partial fix for the guard interrupting/preventing his own reactions to the Hivehand pickup (TODO: investigate this further - I suspect this might only be fixable via script editing, which is something I don't really want to do to ensure max compatibility with other mods)

bm_c2a5f:
* Reworked the APC "arena" a bit to improve combat and player mobility
- Restored(-ish) the building bombing scene from HL1
* Made the RPG resupply crate refill 10 rockets at once, thus ensuring the player will have max ammo (unless they have an edited skill.cfg)

* Changed helipad entrance - removed watch tower sniper spot, opened up the gates instead, replaced the xen launchpad with a healing pool
* Adjusted AI settings so the Xenians and marines will focus on each other before the player

bm_c2a5h:
* Optimization attempts
* Fixed HECU grunt that gets thrown through wall having a gasmask sometimes
- Bathroom door no longer locks behind player to trap them with snarks
* Improved clipping on pipe outside bathroom
* Fixed light in hallway not sounding like metal when hit
* Removed an invisible wall above the fence around the rocket area - yes, it was to prevent skipping the ZECU stairs, but it was obnoxious
* Restored the missing sniper (Tree Frog) radio conversation on the rooftop
* Made the RPG resupply crate refill 10 rockets at once, thus ensuring the player will have max ammo (unless they have an edited skill.cfg)

+ Fixed the guard AI breaking and softlocking for real this time

bm_c2a5i:

* Turned down air-raid siren volume slightly
- Restored Garg chasing the player if they try leaving without killing it
- Restored incoming mortar strikes once the player enters the hallway
* Added a one-way barricade into FAF - this does unfortunately prevent the Garg from chasing you all the way down to the door, but this was the only way to maintain compatibility with the regular game without breaking the AI

KNOWN BUGS:
- The tactical map can still be spammed to the point of crashing the game. Can't fix - there are no delay settings on the map entity, nor do it or the launcher itself take any inputs that I can use to address this.

= INTERLOPER =

bm_c4a3a:
* Prevented player from backtracking to c4a2c/empty void where it should be
- Restored the scrapped tentacle island

bm_c4a3a1:
- Restored old bounce pad behaviour

bm_c4a3b:
* Restored missing brush console at first scripted sequence (vortigaunt plug)

bm_c4a3b1:
* Made the ammo supply drops a bit more varied - shotgun, MP5, 357, crossbow, etc.
* Added some physics clip brushes to prevent potential softlocks in the plug puzzle area (though there may be more I'm unaware of?)
* Attempted a fix for what I suspect is a physics-related crash

bm_c4a3d:
* Added Nihilanth's unused "the truth" line at beginning of map
* "Fixed" softlock by saving/loading once the Controller's picked up a barrel at the beginning of the elevator segment (NOTE: this solution is very inelegant, I'm aware, but short of a code-based fix, I think the only real elegant solution would be something involving cinematic physics, and I'm just one guy who doesn't have the ability to do that kind of thing. this also doesn't fix a similar softlock at the end of the map, the I/O around that one is more intricate and I still need to figure it out)

bm_c4a3d1:
* Attempted fix for beginning softlock
* Moved stasis tubes around to lessen alpha sorting issues

* General enhancements/bugfixes
- Restored from/based on earlier Black Mesa builds and/or Half-Life

+ Made the slamming door near the end not lock behind the player automatically after passing through

bm_c1a1c:
* Fixed xog volume not actually following the drainage water when rising
+ Restored the TEMPERATURE CONTROL sign in the cryo room area; removed some excessive and noisy signposting lights
* Expanded trigger volume for sliding doors so they open a bit more readily

KNOWN BUGS:
bm_c1a1d: Backtracking via the vent from c1a1e may cause some odd behaviour - investigating
bm_c1a1e: Saving/loading causes all swinging crates to reset to default position and can cause the player to get stuck on them - this is an unfortunate side effect of how the swinging crate effect was achieved and I do not know if it can be fixed; investigating. For the time being, stay away from the hook holding the crate when saving/loading
