Cross Fire is one of these games. It has an impeccable aspect and, despite being a totally free game, it has little to envy from other similar pay-to-play titles.
The game system is rather simple, we have to access a server, choose one of the factions and try to eliminate as many enemies as possible to gain experience and be able to access new weapons and game options.
In Cross Fire you'll be able to use more than 40 different weapons, among which you'll find great classics like the AK47 or the M-16, as well as less known ones like Galil-Scope (a light assault rifle designed by IMI) or the MSG90 (a specialist sniper rifle).
