Morbus echos the ideas of Trouble in Terrorist Town, but in a different setting. Almost going for 'The Thing' type vibe where one of your friends is secretly an alien waiting to consume you. As the Brood Alien your job is to blend in amongst other survivors as they kill each other off out of fear and panic. With each kill another Alien is spawned, and your job is to ensure every Human dies...forever!
When you die you can either turn into a Brood or a Swarm. Swarm move fast and spit at people, posioning them, while Broods can blend in to eliminate targets. Im not sure why the game chooses which you get to play as.
The Game can be found by searching for 'Morbus' in The Garrys Mod Servers. Upon loading up Garrys Mod, enter "vgui_allowhtml 0" (Remove the ") to prevent HL2.exe to stop crashing
