About Block Fortress 2
Block Fortress 2 combines block-building, tower defense and first- or third-person combat. You build a fortress, assemble an army and fight to defend your stronghold from relentless enemies across the Blockverse.
Build and defend
Construct your base with walls, turrets, traps and other specialized defenses. More than 200 block types are available, including shield generators, farms, land mines, teleporters and zip lines. You can design anything from a towering fortress to a sprawling castle, then defend it against attacks from four enemy races.
Join the battle
Choose weapons and equipment, deploy an army of specialized soldiers and fight on the battlefield. Your character can use items such as a rocket launcher, mini-gun, plasma rifle and jet pack. Combat takes place in first or third person, and you can team up with friends in co-op to play the campaign, create and complete missions, or build together in sandbox mode.
Explore the Blockverse
Build a home aboard your command ship, then explore 10 planet types, each with its own hazards. Dynamic day and night cycles, severe weather, lava, acid and alien monsters pose additional dangers.
Game modes and creations
Play in sandbox, missions or survival mode. The mission builder lets you create and share levels, from massive battles and stealth missions to obstacle courses and worlds to explore. You can also upload your creations and download levels made by others.
