In boxhead 2play, a shooting game on www.flash-game.net, the rule is quite simple: kill or be killed. You need to collect as many weapons and powerups along the way and always, always keep that multiplier up! You earn more fires, or upgrades for your current arms by increasing your multiplier. Every kill will increase it by 1. The multiplier will go back down over time, and this speeds up depending on how high your multiplier is. Remember to keep upgrading, and your guns, machine guns will become better and better. Be sure and take care of the Box Devils as soon as possible. They can only shoot energy balls at you while you’re not shooting them. Explosives can be your greatest friend as well as your worst enemy. Don’t get too giddy with that Rocket Launcher, the splash damage can seriously put a kink in your zombie killing plans. Have fun!
