Instructions
Take cover behind a wall or other structure to allow time for your shield to recharge. This only takes a couple of seconds but will put you back at full health with enough strength to beat your enemies.
Equip and use stickies, which are neon blue grenades that are scattered randomly throughout each level. You can use them long or short range and they will succeed in killing your enemies in one blast. Press the "LT" button to use the stickies and the "LB" button to equip them.
Take the advantage over your opponent by finding and using power-ups such as active camo or overshield. These power ups are in every level and look like floating spheres of energy. The active camo is a bright blue sphere that will cause you to become invisible to your enemies, giving you the upper hand. The overshield is bright red and will give you an extra dose of strength to outlast your enemies.
Get multiple kills at once using the rocket launcher. These large weapons are located in different places through each level. Shoot a rocket in the center of a cluster of enemies to knock them all out at once and help get you out of a scoring slump.
