boxhead 2 play because its has 10 weapons, endless waves of zombies, 18 levels, co-op play, a deathmatch mode, and its one of the few flash games that have a fun multiplayer.
Well I feel that there is no single best game in Armor Games. Firstly,all the games( well most) are positively fantastic and unique in their own way. Secondly, better and better games will keep coming out(Hooray!) so the list just goes on and on. Thirdly, everyone has their own opinions so someone's "best game" may not be anothers. One man's meat is another's poison I guess.
