How to Play C.O.R.E.
Quick start
Start the single-player mission and review the control settings. Move through the opening area, practise stylus aiming and use short bursts of fire. Read encountered messages and check health and ammunition before moving into the next room.
Controls
The Control Pad moves forward/back and strafes. Slide the stylus on the touch screen to look and aim; the right-handed setup fires with L. Double-tap the screen to jump. Check the selected control setup before using weapon-specific actions, and practise sensitivity before a close fight.
C.O.R.E. — About this game
Commando Jason Crane enters an underground research facility that has lost contact with the outside world. Explore corridors, read the messages left behind and fight the creatures inside with a range of firearms. Movement and aiming are separate, letting you strafe while tracking a target with the stylus. Ammunition and health require attention, so inspect a room before walking into concentrated fire. Learn the aiming sensitivity early and practise small movements rather than sweeping the pen wildly. Progress comes from surviving the current area and finding the way deeper into the facility, where the research site's mystery unfolds.
