Terraria is a 2D sandbox survival adventure game. Edge of Space is a 2D sandbox exploration game. Like peanut butter and jelly, the two will now meet in a tasty cross-over event, bringing Terraria content to Edge of Space, developers Re-Logic and HandyMan Studios announced.

Those attending PAX Prime in Seattle this weekend can get their hands on the Terraria-inspired content at Reverb Publishing's booth (#3436). Among the goodies arriving in Edge of Space is a "cybernetically-enhanced version of Terraria's skeletron boss," Omegatron. Edge of Space is available via Steam Early Access for $11.99. Terraria, meanwhile, launches on iOS today for $4.99.
