What is this, 2015??. We're playing some more GTA 5 with the Adversary Modes in which Rockstar and even community members created new fancy game modes and types for the world to play. There are tons to go through, some old and some new. First up we have Slasher, a Hide and Seek type game in which 1 murderous scoundrel runs around with a shotgun hunting poor souls that only carry a flashlight. Cow Chop Merch:.
