Stalk Lab by Machine
Modified for Sven Co-op by Metro!

Mission: You are scientists sent by a scientific group, tasked with rescuing the specimen that belonged to another scientific group attacked by aliens and military forces. The specimen is inside a secret laboratory that is being infested. You need 4 keycards to open that laboratory (they are hidden in various parts of the map). Once you have the specimen, you must return to the truck you arrived in and leave the area.

Extra Information: The time may decrease when multiple people play the map. It is a non-linear map, and you are likely to get lost or choose a path that others won't take. It is recommended to play with 1 to 3 players, but it can be played with more, possibly up to 32 players. The map is quite detailed and has many high-quality prefabs, so it's normal for your FPS to drop a bit, even though I have optimized it somewhat. You may notice various references to other maps.

I hope you enjoy my map.
