Name every item from Metroid Fusion and Metroid Dread.
Only upgrades to Samus's abilities, as well as her starting abilities, will be included. That means no energy tanks or any other capacity increasing item.
The unofficially named Omega Suit will not be included, since it has no official name (and no function that they player has time to learn about, since you get it halfway through the final boss fight).

Dread had some AMAZING items (and cross bomb is also there). Almost every single one feels like an awesome addition to your moveset (except cross bomb that one sucks). It's really hard to pick a favorite (bet you can guess my least favorite pretty easily), but it really comes down to either the Flash Shift or Storm Missile. Overall, I'd say the Flash Shift just barely edges it out. Love that thing to death.
