It's basically a means of giving your console a traditional arcade interface, with a nice big joystick and six buttons – making it perfect for one-on-one fighting games like Street Fighter II and King of Fighters.
Your Switch console slides into the top of the Switch Fighter, which also acts as a dock and can be used to both charge the system and connect it to your TV.
There's also a 'shooter' mode, which is a grand way of saying you can orient your console in 'TATE' mode, rest it on the top of the controller and connect via Bluetooth, and you'll naturally be able to use two of these devices in tandem (along with two Switches) for one-on-one local battles.
Switch Fighter has a projected shipment window of November 2020, and has a flexible funding goal of just under £95,000, which means the project founders will receive the funds raised even if the project doesn't meet its target. Just over £4,000 has been raised at the time of writing, with 45 days remaining.
Its suggested retail price is a rather steep $153, but if you back the campaign now you can get one for the slightly more reasonable price of $99.
