A fantastic option is Gun Mayhem Redux, an action game that provides players with the chance to explore 10 different story missions, 21 different weapons, 10 different maps, and a whole new mode called Domination.
Mayhem and Guns The objective of Redux is to vanquish the robots by means of your weapons. Begin with the straightforward Al Deathmatch and work your way up to the more difficult objectives later. You have the option of playing by yourself or creating a game with up to three other people. You should always have the ability to pick up new weapons, since this will allow you to destroy your foes more efficiently. Warning: if you go too near to the edge of the pit, you'll end up being crushed.
