A gang of outlaws are about to expand their influence into a nearby town! Defend your town as long as you can, and buy time for the townsfolk to evacuate! Click on outlaws to shoot them. You can regain time by killing enough outlaws to move on to the next level. However, the outlaws have quicker draws on later levels.
Beware Blue Outlaws, as you can't shoot through their shields! Wait until they're about to fire before shooting. Yellow Outlaws throw grenades that take large swathes of your time away. I wonder if you can make it explode on them instead of you... Sound Effects come from freesound.org. Note that I have not tested the difficulty curve, so it may be impossible to reach the fabled Level X.
