Keep Moving...

	Use different weapons...
	Various Steam Achievements...

This is probably the most important thing, always keep moving, never stop. Don't linger in the same room for a long time, don't try to 'camp'. Plenty of weapons in this game heavily punish a stationary target/style.

Even in a 1v1 fight, its important to move: Strafe left and right against Machine gun/Shotgun/Lightning gun/Railgun. Delay your strafes a bit against Nailgun. Keep jumping against Rockets/Tri-bolt.

Try to not chase your opponents. Easiest way to get ambushed, die a horrible way. If your target escaped, go find health and armor, and look for the next opportunity to murder them.

Watch your health and armor. Look for health pickups and armor pickups if you're not full. Taking a fight with less health than you could will almost always end up in you dying horribly. Just try to be annoyed when you're not full health, and be comfortable when you are. Try to remember where the health and armor are on each map, to know where to retreat after a fight.

The starter machine gun is powerful, however you can frag faster. Look for other weapons to pick up whenever you spawn. They are more powerful and easier to kill with.
