Mechanics

Uncompromising, in Antistatic's case, describes a commitment to building on familiar mechanics. If it's in Melee, it's probably here. For peace of mind, though, here's most of what to expect:

Some new mechanics include:

Controllers

Officially supports GameCube (via USB Wii U/Switch adapter, native mode), 360/XB1 (and compatible), PS4, and keyboard (keyboard is not recommended).

Button/key rebinding is in progress. Basic rebinding is available, more in the guide.

If you can already use GCN controllers in Dolphin, it should work in Antistatic too. In the future, this process might be an automated option.
