Crossplay

Is Never Split the Party crossplay?

Never Split the Party is only released on one platform, so there is nothing to cross-play with.

Steam's own store page lists cross-platform multiplayer for Never Split the Party. That confirms it exists, but not which platforms pair up.

Never Split the Party is an ultra social rogue-like! You're one of four adventurers joining together to explore a procedurally generated dungeon, amass powerful upgrades, and cooperate with your fellow adventures to conquer and crush the evil dungeon champions!
