Here is a quick reminder of the game’s controls:
Light Weapon: Press and hold on the screen with one finger. Light weapons can overheat if used for too long. Release your finger to allow your weapon to cool down. If you are playing on iPhone 6S / 6S+, you can also use 3d touch to zoom.
Heavy Weapon: Press and hold with two fingers to aim, then release to fire. Heavy weapons are limited by ammunition which recharges over time. If you are playing on iPhone 6S / 6S+, you can alternatively use 3d touch to activate your heavy weapon.
Mounted Weapon: Unlocked after completing Chapter 2, double tap anywhere to fire your mounted weapon at all enemies on screen. Mounted weapons are also limited by ammunition which recharges over time.
Melee: Tap on the red melee icon to engage in melee combat:
Ensure you do this before the two bars line up or the enemy will attack you! Once in melee combat, stop the melee indicators when they line up in the middle to strike. The closer these are to the middle, the more damage you’ll do.
Shielding: Tap on blue shield icons to block enemies before the two bars line up. You have a limited number of shield charges which you can track in the bottom left of the screen.
