Dead Island : Riptide - 28 Geeks Later

                    
Zombies are now fast, powerful and extremely dangerous, they move fast and they will swarm the player and beat them to death quickly if they are not careful. The player has been given a small amount of health regeneration, which helps between battles, but it won’t save you if you get swarmed. Player now swings his weapon faster, moves faster, has better stamina and has 100% boomerang. There are also new experimental weapons added, including the revolver that Rick Grimes himself uses*. *Not Rick Grimes’ actual gun, but a faithful replica.
