FWKZT Zombie Survival
Zombie Survival is a massive gamemode where humans are pit against a zombie horde. Once a human dies, they become a zombie. Additionally, humans must protect glowing structures called sigils that randomly spawn throughout the map and allow for inter-transportation. The humans win if they survive a certain amount of time or complete objectives. The zombies will win if all humans die or all sigils become corrupted.
As the game goes on...
Humans will be able to unlock more powerful weapons over time along with being able to construct barricades and deploy weapons to counter the zombies. They hold the ability to travel between sigils and must work as a team to stay alive. Zombies over time will unlock more powerful forms and being able to move as hordes than can sustain more damage. Every round also introduces a boss zombie which will have devastating effects on the humans without teamwork!

Trouble in Terrorist Town (TTT) is a gamemode included with Garrys Mod. The game is about a group of "terrorists" who have traitors among them, out to kill everyone whos not a traitor.
A small number of players is selected as Traitors, who have to kill all the Innocent players (ie. the rest of the players). Those innocents know they are in the majority, but they do not know who is Traitor and who is not.
The Traitors must use the element of surprise and their special equipment, if they are to succeed. The Innocent just have to survive, which means finding out who the Traitors are and killing them before they kill you. Of course everyone is holding a big gun, and everyone looks suspicious...
