Serious Box Solid is a multiplayer versus total conversion mod that adds a wholly new unique gameplay mode not seen before in Serious Sam; Infiltration!
Taking inspiration from Metal Gear Solid, players are pitted into two teams, Snakes and Guards. Snakes must sneak prone and use a variety of stealth equipment, including CODEC and a box disguise, to find and activate mission objectives that ultimately help them gain the weapons needed to kill the Guard team, while not being seen! In the meanwhile, Guards have to be on the lookout for those pesky Snakes and kill them all before they accomplish their mission! Only guards have access to starting weapons; Snakes must avoid detection to survive.
As of 1.1, the mod also features some singleplayer content! (VR Missions mode, Campaign Alpha)

Main features:

* New gameplay modes with predefined rules, Infiltration, Snake vs Snake and Kerotan Rescue
* New prone and walking animations! Sneak around like a boss! (Big Boss, even)
* New Knife melee weapon with custom animations!
* Disguise yourself as a BOX! YOUR DESTINY IS TO BE IN A BOX!
* Disguise yourself as a BUSH! Become a true bushman!
* New Smoke Grenades that you can use to conceal you and your teammates!
* Fool enemies with fake CODEC calls
* Scripted, objective-based multiplayer gameplay! The more objectives you complete, the better your chances!
* Redone menus, music, texts and sounds to fit the Metal Gear universe
* Lots of player models specifically made for the mod, including Solid Snake, Big Boss, Guards, Major Zero and Sigint
* Custom-built Warehouse, Jungle, Night Hunt, Tanker, Shadow Moses and Middle East maps specifically made for the new gameplay mode, and lots of additional other maps for the new gameplay modes!
* Neutral animals including alligators and snakes that you can hunt, or avoid!
* Singleplayer/Co-Op VR Missions mode is now included!
* Fine cuban cigars...

Caution!!: This mod is a total conversion and WILL likely conflict with any other weapon altering mods! To be perfectly safe, play the mod without having such other mods active. The mod has its own menus as well which may clash with other menu mods (or mods with custom translations).
Swap between mods using the Extras -> Workshop Content menu. The mod does not support standard SP or CO-OP play.

For instructions on how to play, check out the included videos for a feel of how the mod plays like, or read the how to play guide! You may also wish to try the mod out in singleplayer VR mode to see how the levels play out.
The mod requires the Jewel of the Nile DLC because it uses many assets from it. If you cannot see custom menu texts, it's likely because another large mod is overriding them (possibly Solais's resources), if that's the case you can try disabling them, though it's not essential for playing the mod.

Non workshop version of the mod can be downloaded from here (COMPLETE with parts 1-4):
https://www.dropbox.com/s/dchm7pdg3d2ex7u/Z5_SeriousBoxSolidCOMPLETE_pts1_4.gro?dl=0
And Part 5: https://www.dropbox.com/s/0e1amxtdgfvk3ll/Z6_SeriousBoxSolidPart5.gro?dl=0

(Save the .gros to Content/SeriousSam3, same functionality, but keep in mind you need to move them somewhere else when you want to disable the mod. If you had older .gros of the mod already installed, please delete them before using this one!)

If you get the "workshop content update failed" error message, it's a problem on Steam's end and we cannot do anything about it, unfortunately - in that case it is best to restart Steam and try again (especially if it doesn't even start downloading the mod). If restarting doesn't help, try resubscribing to the mod (Unsubscribe -> Launch game in moddable -> Exit -> Subscribe -> Launch moddable game again).

CHANGELOG FROM 5.0 to 5.1 (part 5 only):

- Raised amount of Tranquilizer Rifles per map from 2 to 3.
- Updated translations for lasergun, version, misc stuff. May or may not work depending on load order.

CHANGELOG FROM ??? to 5.0:

- Added Part 5, updated parts 1 & 2 with miscellaneous fixes.

CHANGELOG FROM 1.5 to 1.6:
- Added more content to Part 4 (see that for details).

CHANGELOG FROM 1.4 to 1.5 (part 3 only update):

- Added "Operation Grinch" christmas Infiltration map!
- Added "Showdown" Snake vs Snake map
- Added Big Boss (Santa) and Zero Suit Samus (Santa) models
- Added Peace Island (Fast) alternate version
- Players now take damage from going to deep water in Peace Island

CHANGELOG FROM 1.25 to 1.4 (part 3 only update):

- 2 new Infiltration maps, Peace Island by Finzy and Omaha Beach by Pan
- New gameplay systems, including Fulton Recovery and better objective handling
- New player models:
SNAKES: Mei Ling, Kazuhira Miller, Big Boss (Peace Walker), Raiden (Default), Funky Finzy (Various Camos), US Soldier, Spy
GUARDS: PMC Troopers, Haven Guard, Tea

Older changelogs removed to save space, they're still available on the Seriously forums if you really want to read them though. :P

KNOWN BUGS:

- Floating crumbs in Rassvet Jungle in some places.
- Black screen when joining ongoing games sometimes. This is a game bug we can't fix, you just need to wait until the current round finishes.
- The game ending script in Middle East Warzone may break if the player exits the helicopter before getting teleported. If this happens then all the guards must still be killed in order to win.
- Guards' exclamation mark ability does not work with custom assault rifle mods, so it is recommended to use included mod weapons for the AR
