In the late '00s, before every game became a MOBA and then pivoted to become a battle royale, it seemed like every other game was a shooter with some sort of gimmick to make it stand out from the Calls of Duty and Battlefields. From gravity manipulation to doing drugs, here's a bunch of the oddball gimmicks developers came up with to sell us on their mid-budget manshoots.
Haze: The One With All The Drugs
TimeShift: The One That Actually Shifted Through Time
Fracture: The One With The Movable Terrain
Singularity: The One With The Time Manipulation Device
Inversion: The One Where You Manipulate Gravity
The Darkness: The One With The Tentacles, Demons, And Feelings
Lost Planet: Extreme Condition: The Cold One
Army of Two: The One With Best Friends Forever
Area 51: The One With The Alien Mutation
Wet: The Slippery One
