It's not just a mod, but the whole new game...
Several years ago, a secret paranormal activity research lab was founded in the cold ice of Antarctida. One month later, an accident occured. During a careful examination of the newly discovered teleport, scientists faced the unforseen consequences.
The teleport was two-sided. As a result, some unknown creatures broke into the lab through the teleport. At this moment, the teleport is not activate anymore, but the lab is still full of monsters. It's not a big deal to kill them all, but we're very interested in the world they came from.
Your task is to get an access to the control room and use the teleport to get to the aliens world and destroy their reproducer.
Don't you be confused that this reproducer is 7-8 meters long though...
You'll get a special suit that will protect you from any kind of damage, as well as any needed ammunition.
This is one of the most interesting cooperative mods for Serious Sam: The Second Encounter. Instant must-have for every STALKER fan!
Attention! Requires Serious Sam Gold Deathmatch maps! https://grorepository.ru/mod/serious-sam-gold-deathmatch-maps
