Throughout the game, you must collect various Items to improve the firepower and health of the Guardian. Items may be found inside capsules like the one shown to the right, some may drop from enemies, and some may be granted after completing a Corridor. You must shoot the capsule to obtain whatever item it contains.
Blue Chip
Red Chip
Heart
A Blue Chip restores 20 spent chips. It also restores a tiny sliver of health.
A Red Chip restores 500 spent chips. It also restores two hit points of health.
Collecting a Heart will restore five lost hit points of health.
Energy Tank
Blue Lander
Red Lander
Picking up an Energy Tank will completely restore the Guardian to full maximum health.
A Blue Lander allows the Guardian to store more energy by extending her health meter by one hit point, and it will refill her health. The Guardian also earns these health extensions when her score reaches certain levels.
Each Red Lander increases the maximum number of chips that the Guardian can store, up to a maximum of 4000 during the normal gameplay mode, and up to 6000 in Corridor Rush mode. It also refills the Guardian's health. Note that higher Chip count also increases the main weapon’s beam width.
Rapid Fire
Attack Up
Defense Up
The Rapid Fire tile increases the Guardian's rate of fire when you hold down the main weapon button. Up to level 5 Max.
Collect the Attack Up gun tile to increase the amount of damage that the Guardian's attacks inflict on enemies. Up to Level 4 Max.
Collect the Defense Up shield tile to decrease the amount of damage that enemies can cause to the Guardian. Once her Defense is at level 5, the Guardian will also gain movement speed. Defense can be increased to a maximum of 7. Note that acquiring these shields has a side-effect of changing some of the enemies in Area 0.
Keys
Doorways that have symbols on them require the key with the same symbol in order to access what's found on the other side. Keys are obtained by defeating bosses found at the end of particular corridors. Finding these keys will expand the amount of labyrinth that the Guardian can explore.
