As you may know, AssaultCube is an open source, multi platform, lightweight Counter Strike clone.
The main differences between the two games is that AssaultCube has only 5 guns and there is no bomb to planting/protecting. In AssaultCube, both teams have to steal the enemy flag and take it to their base.
To install AssaultCube on Fedora 19, add the rpm fusion repository first:
