Vlambeer's Nuclear Throne is available to buy from Steam Early Access for Ł9.99.
Nuclear Throne, formerly Wasteland Kings, is an action roguelike from the team behind Ridiculous Fishing and Super Crate Box.
The Early Access version, right now, includes four playable worlds, seven playable characters, two boss fights and plenty of weapons and skills.
When the finished version launches it'll include at least four more worlds, secret worlds and additional characters.
"Join us while making Nuclear Throne through the livestreams on the game website and be the first one playing new builds every week," the team said.
"We hope you enjoy the ride with us, as we have no clue where we're going to end up on this project and that's really fine with us."
