“What’s a surefire way for a Steam game to reach more Steam users? Steam Deck support! That’s just the tack adopted by Cthulhu’s Reach from The Fine Arc and First Break Labs. This Steam Early Access title is a horror-themed bullet heaven shooter that features 4-player online co-op. Now that it’s safely playable on Steam Deck, players can battle the terrors of the deep on the go,” says Co-Optimus.
