The Rules:

1. If it moves, shoot it.
2. If it doesn't move, poke it with your turret and then shoot it.
3. When in doubt -- Shoot It!!
4. Overkill works.
5. Just because it breathes doesn't mean it should.
6. If all is going well, it's an ambush.
7. If it's not moving shoot it anyway, it might move later.
8. Always remember your weapon was made by the lowest bidder.
9. If the enemy is in range, so are you.
10. Don't look conspicuous, it draws fire.
11. If it's stupid and it works, it ain't stupid.
12. When in doubt, empty your magazine.
13. The easy way is always mined.
14. Try to look unimportant, the enemy may be low on ammo.
15. Teamwork is essential, it gives the enemy somebody else to shoot at.
