Free Steam Game Crashphalt Becomes Unofficial Undertale Online Launcher
Indie developer RetroSpecter has revealed on Reddit that his free Steam fighting game Crashphalt, released in 2018, is being used by players as a launcher for an unofficial Undertale multiplayer mod. The game, a 2D versus action title supporting up to four players locally, saw its concurrent player count jump from single digits to over 100 in 2022 after a user published a method to enable online co-op for the Undertale Together mod via Steam Remote Play Together. Crashphalt's Steam reviews have since grown to about 550, with 95% positive, earning an Overwhelmingly Positive rating. Many of these reviews mention Undertale, which initially confused RetroSpecter. He investigated and found that his game was chosen because it supports Remote Play Together and is free, though he noted many other games meet those criteria. Rather than being upset, RetroSpecter said he is pleased the game has found new life, especially since Undertale inspired him when he started developing. He also jokingly invited Undertale creator Toby Fox to collaborate on a future project. RetroSpecter is currently working on a roguelite puzzle game called Draftula.
