Defend. Upgrade. Prestige.

A little salvage.
A stronger beginning.

Start with your own shots

Defend a stationary ship with the manual Main Cannon. Destroy incoming asteroids for Credits, then buy your first automatic cannon.

Build a working arsenal

Purchase and upgrade ten automatic cannon tiers, from precise shots to piercing, plasma, chain and full-field attacks. Every 50 and 100 levels brings a damage milestone.

Choose when to begin again

Clear wave 100 to unlock Prestige. Push further for more points, then restart with permanent bonuses and invest in Offense, Economy and Survival.

Make the moment count

Unlock eight active abilities, including Overclock, Gravity Snare and Full Barrage. Take on minibosses, bosses and their escorts.

Keep developing your build

Discover Research, complete projects and equip modules. Track local achievements and lifetime statistics as your runs grow.
