Armed with only your handgun, shoot at your armed enemies before they take you down first. Aim and fire your weapon with your mouse and use the space bar to reload. Act quickly or too many enemies will pop up and drain your health. Take them down with two shots to the chest for 10 points or get a score of 15 points by finishing them off in one blow with a carefully aimed headshot. Once you defeat all of the bad guys, you're ready to move on to the next level. Be careful not to die though; or it's back to level one for you.
