Black Mesa: Unforeseen Consequences (2/5)

A campaign set in intricate Black Mesa facility, can you fight your way through the maze-like hallways and escape the zombie ridden facility?

All credit goes to Crowbar Collective for materials, models, sounds and everything else included that isn't base L4D2 content.

Fun Fact: This workshop upload used to be 800 Megabytes, because the boulder textures used in this specific map were all 4K (4096x4096) Resolution textures. Totaling to over 302 Megabytes of just boulders.

WARNING: You may crash loading the final two maps, this is because these maps are very heavy and your game may not have enough RAM or power to load them as well as your current mods. I can recommend going through and

- Removing any workshop maps you do not play anymore.
- Swapping full model swaps (Survivors, Guns) to just a texture swap.
- Launching the campaign directly to that map you crashed on, this works but you'll be missing all your equipment. Luckily both maps will supply you with a surplus of guns and equipment before a big event.

Thank you SO MUCH to Sherriff Huckleberry for lowering file size and hopefully fixing that annoying missing content bug!
