Overkill

Civilized society has collapsed and you have been hired as a mercenary with a mission to kill all you cross. On the Battlefield use an array of increasingly powerful weapons (AK-47, M4, SCAR, RPG, P90) to eliminate anything that stands in your way. A bounty is paid for everything that is killed and destroyed, and with the reward you can buy weapons or upgrades. You will fight through 20 waves in each of 5 Battlefields that the game offers. After beating 20 waves there is a massive Hell wave. *** OVER 6 MILLION PLAYERS ***
