To complete Mayhem Triple, you will have to kill hundreds and hundreds of rabbits but rather than being an exercise in plentiful poaching, Dustin Gunn’s game concerns an alien invasion. The aliens just happen to look like bipedal rabbits, who wander back and forth quite nonchalantly. They’re not particularly bright but it would appear that they’ve been breeding very much in the manner of their Earth counterparts. There are loads of them, which means you’ll need all to make use of all the Max Payne/John Woo style diving, dodging and shooting at your disposal. Mayhem Triple is The Specialists mod, but single player and in 2d. It’s also completely free.
