How to Play Pokemon Infinite Fusion on Steam Deck

Gotta Fuse 'Em All

The world of Pokemon Infinite Fusion is a strange and somewhat scary place, full of Eldritch-level horrors beyond our comprehension. Just because we CAN fuse Pokemon together with DNA splicers doesn’t mean that we should, even if the results are somewhat hilarious at times. However, for those hoping to play this game on the go, the Steam Deck is a great home for it, alongside your favorite mobile devices. If you’re one of the many that love their Steam Deck and also happen to love Pokemon, fan games may be the perfect way to go, so let’s find out how to get this particular title on our favorite portable PC.

If you’re hoping to get the most out of this game, make sure to download the Vibrant Deck plugin to give your screen an extra boost of color.

If you like the game enough, you can always add custom artwork and icons to make the experience even more legit. While we may never get a Pokemon game like this out of the mainline franchise, we can always count on fans to do what Nintendon’t.
