Blaster Master/Items and Upgrades

Items
All three of these items will either appear grey, or flashing red. Grey capsules provide one additional bar of power, while flashing red capsules provide four additional bars of power.

Gun power
Note that there are 8 different levels of firepower, and there are 9 states for your gun meter, including empty and full. If you start out empty, you will reach the eighth level of firepower when your meter is 7 units full. Likewise, if you start out full, you will reach the lowest level of firepower even if your meter still has 1 unit full.

SOPHIA weapons
In addition to her main gun, SOPHIA is also equipped with three special weapons that you can fire, provided you have a supply of ammunition. Collecting each of these capsules gives you a supply of 20 units of ammo for that particular weapon. To activate a weapon, you must press and highlight the desired weapon. To use the weapon, you must press.

SOPHIA upgrades
Every time you defeat an area boss, you will obtain one upgrade that is applied to SOPHIA upon collection. Some upgrades increase SOPHIA's firepower, while others increase SOPHIA's mobility.
