AM2R/Items

Energy and Ammunition
Throughout the game, some enemies will leave items behind after you destroy them. Initially, the items may be energy or missile ammunition. After collecting the Super Missiles and Power Bombs for the first time, ammunition for these weapons may appear as well. Small energy orbs provide 5 units of energy. Occasionally, stronger enemies will leave larger orbs that provide 20 units of energy. Each missile that Samus picks up adds two missiles to her supply, up to her current maximum capacity. Each Super Missile and Power Bomb collected increases her supply by one.

The current amount of energy and missiles in Samus' possession is always shown in the upper-left corner of the screen. Energy is shown by a number ranging from 0 to 99, with squares accumulated for every Energy Tank that Samus collects. A full blue square represents another 100 units of energy which will empty out if the current energy tank is depleted. Missiles are shown ranging from 30 to the maximum capacity of 250. Super Missiles and Power Bombs can reach a maximum capacity of 20.

Power-Ups
Many items besides Missile Packs and Energy Tanks are closely guarded by Chozo statues. They are contained in energy orbs that only Samus' beam weapon can disrupt in order to claim their contents. Other items are in the possession of bosses which you must battle and defeat in order to obtain.
