Construct a fortified base and defend it against a range of different monsters in Block Defense Alpha, a strategic survival game where you'll get to work together with other players! To get started on your first game, you'll need to select one of three game modes: easy, hard or PvP. In easy and hard, you'll find yourself placed against a range of monsters like zombies, giants and phantoms. In PvP however, you'll go head to head against another team of players, and working together with your other teammate try to withstand their series of attacks.

Depending on how many attacks you survive, you'll earn coins and XP for your character. These can then be spent on new abilities, weapon upgrades, and stronger defenses to use in future games!
