Metroid Prime 2: Echoes/General Speed Tricks

General Movement

Listed are various movement forms and their speeds:

• Standard walking (10.8)
• Walking while holding L (11.8)
• Rolling (20)
• Boosting (up to 40, depends on how flat of a surface you boost on)
• Screw attacking (20 but begins decelerating eventually)
• Roll Jumping (16-17)
• Extended Dashing (32+)

Some other notes:

• Holding L also improves jumping height/speed the same way it is better for walking
• Grappling is faster than screw attack, so in rare situations where you have both items and can use either, then you should grapple
• Screw attacking starts at 20 speed but decelerates as you start to fall during the screw attack. So, if you don't need to go a particularly far distance, then try to minimize the time between screw attacks
• You can cancel any of your first 4 screw attacks by spamming B. This can help you land sooner if you have already screw attacked far enough
• You can cancel the Super Missile cool down by bringing up Scan Visor after firing it, saving around a second in some situations
• If you have cannonball, you can open doors that previously had a blast shield on them by simply touching the door
