About Just Sign!

Just Sign! is a tower defense game for 1 to 4 players. You mine, chop, refine and craft turrets to protect objectives from enemies such as ladybugs, zombies and flying whales. You can play solo or team up on the same couch or over the internet; the campaign is designed for solo play as well as co-op.

Build your defenses

You build and combine different turrets to counter different enemies. Options include ballistae, flamethrowers, rail guns and cannons. During each map, you also refine resources, craft equipment and reload your defenses.

Protect objectives

Work together to stop enemies from destroying machinery, beehives and ships. Different enemy types call for different tactics, and you need to communicate, divide jobs and plan your defense. Strategies that work on one map may not work on another.

Dynamic maps

The maps add hazards and moving objectives to the defense. You avoid traffic and falling rocks, chase minecarts for resources, get on top of trucks, and move bridges and platforms to reach your goals. Some objectives include defending your ship from a kraken.
