Barrage

Barrage is a rather destructive action game that puts you on a shooting range with the objective to hit as many dummy targets as possible within 3 minutes.

You control a gun that may either fire small or large grenades at soldiers, jeeps and tanks. Targets are fast paced and require careful aiming as it takes half a second to reload the gun. In addition, you have to keep an eye on your ammo and reload in time.

(If you see the windows mouse pointer after the game started simply click to minimize the game.) Then maximize it again and it should work.
