Valkyrie Initiative and solo developer 70`Strike have announced Kettlebell: Inferno Hotel, a high-speed 2D platformer coming to PC via Steam and GOG, PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, and Nintendo Switch. No release date or pricing has been confirmed.
The game casts players as Mr. K, an ordinary office worker who ends up in hell following an absurd accident. Hell, in this case, takes the form of a bizarre hotel where each floor is locked down and packed with hazards. The goal is to fight through every floor and reach the Boss to sort out the cosmic mix-up.
Kettlebell: Inferno Hotel features over 40 handcrafted stages spread across nine themed floors of the Inferno Hotel. Settings range from scorching factories to a park for "homeless souls," leaning into the game's surreal, darkly comedic tone. Enemies and bosses skew grotesque, and the game offers two distinct modes: Classic, which uses a traditional lives system, and Arcade, where players can't die but take heavy score penalties on hit, pushing for a high-score chase instead.
Visually, the game uses hand-drawn pixel art with frame-by-frame animation. The soundtrack, composed by the developer, blends jazz, 80s disco, and blues into a retro-flavored mix.
Steam Playtest and Exclusive Rewards
Alongside the announcement, Valkyrie Initiative opened sign-ups for a Steam Playtest. Players who participate and meet certain conditions will earn exclusive in-game items at launch, including a golden kettlebell skin, a "stinky" kettlebell skin, and a yellow shirt for Mr. K.
The top-tier reward requires S-ranking every stage in the Playtest build, unlocking the "Golden Run" Steam achievement, wishlisting the game, and following Valkyrie Initiative's Steam publisher page. Other rewards are tied to separate achievements and participation milestones. A specific start date for the Playtest has not yet been announced.
A Retro Love Letter with Its Own Identity
70`Strike is the work of solo developer Ksayfar (Dmitriy Bukhtatov), whose previous title was Skelethrone, a darker, more punishing action game. In a statement, Ksayfar described Kettlebell: Inferno Hotel as a deliberate shift in tone: "After working on a dark, challenging world like Skelethrone, I wanted to make something lighter, weirder, and more playful, without losing the punch and personality that make action games memorable."
He cited Earthworm Jim, Boogerman, Bubba 'n' Stix, and Sonic as key inspirations, layered over a hell setting loosely inspired by the Divine Comedy. The result, he said, aims to be "fast, surreal, handcrafted, and intentionally a little odd."
For a new IP from a solo developer, the wide platform spread across both current and last-gen consoles is ambitious. How that translates in practice, particularly on Switch, remains to be seen. Players interested in trying the game early can request Playtest access now through its Steam page.
