Levels have a set number of randomly generated waves of enemies, one or more random midbosses, and a random boss (from a pool for each level.)

Mid and level bosses drop a selection of three items, of which you can choose one to take. Items dropped include weapons, usable items, passive items, ship upgrades (weapon power/speed/armour), repairs, and coin purses if there is nothing desirable available.

Before each level you can choose between two planets to visit, and after each level you will visit a shop to upgrade/buy weapons and items.

Rank increases when you score points, and decreases when taking damage or using a bomb. There are five levels of rank, from very easy to very difficult. Rank begins at level 2/5.


Scoring[edit]


Kill enemies and collect coins dropped for score. Enemies are spawned in waves, and each wave survived contributes +5% to a score multiplier. Each wave completely cleared contributes a further 5%. Multiplier is reduced by 50% if damage is taken, and caps at +100%. Score per enemy is increased based on the current rank level.

Story[edit]

Fleets of robotic ships are invading planets and causing destruction all over the galaxy. It is up to you to search for the source of the electronic legion and shut it down once and for all.
