Morbus is a mod (gamemode) for a game called Garry's Mod which is built off of Half-Life 2. The aim of Morbus was to create a scary multiplayer game where players are forced to make hard decisions on who to trust which will inevitably determine their fate and the outcome of the round. Players are either humans or aliens. The aliens can disguise themselves to look like humans, however to infect a human they must transform into their true alien form. Based on the scenario and situation the aliens must utilize a number of different tactics and strategies to infect and turn all the humans into aliens.
