What kind of game is this?
Defend regions from a canyon to an orbital gateway. Place towers beside roads, adjust positions and targeting as enemy waves change, and protect core durability for a better clear result.
Combine slowing, area damage, armor penetration and support. Liberating regions unlocks more tanks; at level 3, choose one of two evolutions. Research applies from the next deployment, while battle specializations last for that deployment.
Your first steps
- Choose a region and difficulty on the map. Click empty build points to form your first defense, then start the wave.
- Read the wave forecast and fill gaps in your defense. Click built towers to upgrade, sell or change targeting priorities.
- Survive a region's 20 waves before challenging the next. More clear stars award research points, so preserving core durability aids progression.

Helpful playing tips
- Pair slowing and area attacks where enemies bunch up. Add armor penetration if armored foes survive.
- Spawners leave offspring when defeated. Keep a rear defense to finish them off if your front towers focus only on leading enemies.
- Risk contracts increase both rewards and enemy strength. If the core is damaged, check upgrades and skill cooldowns first.
Saving and playing together
Where is progress saved?
Battle progress, cleared regions and research autosave in this browser without automatic device sync. Starting a new deployment may replace the current battle save.
Can I play with friends?
A solo game. Before a wave begins, take time to compare tower roles and your budget.
