When it comes to shooting games, the Desert Rifle game series is one of the best, if not the Best Game Ever. The graphics presentation and visual effects are great. But once you have played all the sequels and finished all the missions, then there is nothing more than playing the game all over again. So the alternative is to find games like Desert Rifle. One is Storm Ops where you are a soldier; shoot and kill the coming enemies. Survive and complete the twenty five waves and you can still play as much as you want. Another interesting game is Last Line of Defense.
A virus had killed everyone and you are among the survivors. Kill all zombies coming towards you using your powerful guns and ammo. Another game is Castle Guardian where you have to kill all enemy soldiers before they destroy the castle’s wall.
