The 2 best free army games are crossfire and AVA. AVA is considered better in the way of graphics and professionalism, but I personally like crossfire better. AVA is built for custom or newer laptops that can support its high graphics so most of the people that play lag alot, while crossfire does have its laggers, but its no where near as bad as AVA. Also crossfire has a few more modes including mutation mode and ghost mode <---- love those. You can try crossfire at z8games.com or AVA at ava.ijji.com
