A Situation of some Gravity
From SmashWiki, the Super Smash Bros. wiki
A Situation of some Gravity is a single-player event match in Super Smash Bros. for Wii U. In it, the player controls Zero Suit Samus and must defeat Rosalina & Luma in a 1-stock match. Zero Suit Samus has her gravity set to heavy, while Rosalina's gravity is normal. Warp Stars appear more often compared to other items.
Clearing the event on normal or hard difficulty within 50 seconds awards a Super Scope Beam Whip equipment.
