Bazookas...
	Flame thrower...
	Headshots...
	Reloading...

The blast radius of a bazookas is large enough to take out multiple enemy soldiers. Always try to shoot them in the middle of crowded areas to take out as many soldiers as possible.

The flame thrower is used to force an enemy to run, and therefore be unable to shoot. Use this tactic to set as many enemies on fire, take them out individually without the risk of getting shot at.

Headshots cause more damage and will earn a score multiplier as well. Take some time to aim carefully for headshots whenever possible. This is particularly important because battles cannot be replayed. You must try to perform your best in each one to get the most money for upgrades. Consider waiting for enemies to stand still and reload before taking them out cleanly. Learn their patterns to see who shoots first, then take them out individually.

If you can finish a wave of enemies before moving to the next point, your weapon will reload automatically, saving time. Do not waste time reloading during the fights unless you are actually out of ammo. Upgrades You must upgrade your weapons in order to be successful. Try to have more than the minimum required weapon power to pass the missions. Upgrading requires time. To be efficient, start one or two upgrades while trying two other missions. Play them until you are maximum, then begin to upgrade those weapons. Keep the weapons upgraded evenly for use in the main storyline.
