Overkill 3

					
Grenades:

Grenades must be purchased with premium currency. You will be given a few at the start of the game. Do not bother purchasing more of them.
Reloading:

Use the “Reload” button after killing an enemy or two adjacent enemies. This will immediately bring you back into cover, giving you time to move the crosshairs to a new target.
Saving ammunition:

Shoot explosive objects to take out nearby enemies and save ammunition.
Snipers:

When snipers are present, red laser sights will slowly target you. They can hit you while you are behind cover. After a short amount of time the sniper will shoot. To avoid being hit, take out the sniper before they can fire. Always make snipers your top priority to target.
Upgrades:

Spend credits upgrading accessories that will increase important stats, such as accuracy. Do not spend credits on cosmetics such as new colors and stickers.
