Samus's primary weapon is her Arm Cannon, which fires various beam types. These beams often stack, combining their effects.
- Power Beam: Your default weapon. Fires a single shot. Can be charged for a more powerful blast.
- Wide Beam: Fires three shots horizontally, increasing your area of effect. Essential for opening Wide Beam doors and pushing specific blocks.
- Plasma Beam: Increases beam damage and allows shots to pierce through multiple enemies and certain materials.
- Wave Beam: Allows your beam shots to pass through walls and obstacles, hitting enemies or switches on the other side.
- Diffusion Beam: When charged, creates a large explosion upon impact, damaging enemies in an area.
- Omega Beam: A temporary, extremely powerful beam acquired from an Omega Cannon, used exclusively to destroy E.M.M.I. units.
Each beam upgrade significantly enhances your offensive capabilities.
