Jagex’s new multiplayer FPS Block N Load, an intriguing-looking 5v5 game that combines elements of Minecraft and Team Fortress 2, is now available for PC on Steam. The game was previously available by way of a beta, but today, April 30, marks its official release

Block N Load normally sells for $20, but to celebrate the game’s official release, Jagex is offering it to everyone for free this weekend only as part of a Steam Free Weekend promotion. This offer, along with another discount that should make the game $15 for its launch week, does not appear to have gone live just yet. But keep checking the game’s Steam page to see when it does.

Six Block N Load characters are available out of the gate, each of which have different skills and attributes. Check out the Block N Load launch trailer above to see these unique characters in action.

Block N Load’s maps are anything but static, as players can use the game’s building tools to shape the world around them. Jagex says this means no two matches will ever be the same. For lots more on Block N Load, check out GameSpot’s in-depth hands-on preview in the video below.

“We’ve tried to do something different with Block N Load. We wanted to make a game where building is as important as bullets, smarts are as important as skills, and players could contribute to their team in their way,” Block N Load vice president David Solari said in a statement. “We can’t wait to see the creativity and invention of those that play Block N Load now that it’s live. Today’s launch is only the beginning. We have a player-first mentality, and look forward to an exciting journey with the players as the game evolves.”
