Jagex, the developer of fantasy MMO Runescape, is working on a new first-person shooter called Block N Load.

The cartooney online multiplayer shooter is a combination of 5v5 team-based first-person action and strategic construction. Teams build defensive and offensive emplacements before attacking the enemy base. It looks a bit like Team Fortress 2 meets Minecraft.

Six heroes are available, including Cogwheel, a weapons-obsessed robot; Mexican ninja O.P Juan Shinobi; and Doctor Eliza Doolally, who likes chemistry.

Unlike previous Jagex games, Block N Load is not browser-based, is not free-to-play and is not an MMO.

You can put your name down for the beta, scheduled for launch by the end of this year, over at the Block N Load website. A Steam release is planned for 2015.
