What each player can do here
- Run into a station to use it: a turret (aim and fire, short range), the engine (fly the ship), the shield (turn it around the hull), the Yamato cannon (a big hit, then a recharge) or the map.
- Playing alone, you get an AI space-pet, a dog or a cat, to send to a station. It handles the guns and the shield well but cannot fly the engine.
- The same stations. Drop a gem into a station to change how it works; once the ship is upgraded, each station takes two gems.
If your skill levels differ: PSNProfiles' no-damage tip keeps one player on the shield for most of a level while the other flies and moves between the guns.Our suggestionGive the shield to the newer player and let the steadier one fly and call the swaps. How to split the roles
The four levels
Part 1 of 2. Free enough captured friends to reach the boss.
- BothEach campaign is four levels and a boss fight.
- BothIn a level, shoot open the cages and beat the enemies that come out to free captured friends. Five of the ten in a level open a heart-shaped portal onward.
- BothThe levels are Lost Gates, Stellar Collapse, Flooded Ruins and Maelstrom Core; The Star King is the fifth stage.
Where people tend to fall
- The first level here is full of security guns; the Steam guide calls it the easiest place for the Entrapment achievement.
The Star King (boss)
Part 2 of 2. Strip his shields and keep moving.
- BothClear the shields circling him quickly, before they come back, then hit his body. The Steam guide strips the whole ring by firing two weapon stations at once.
- BothUse default or Power turrets. Beam shots don't go through his shields, and Beam or Metal gems slow a turret's fire.
Boss
King CepheusThe final boss
- Shield ring: Shield orbs circle him and grow back fast; once some are down, any part of him can be hit.
- He sends two sets of homing shots from different angles. They can't usually both be blocked, but moving lets them bunch up so one shield turn covers both.
- Raising his arms summons three spiked chains that can't be destroyed and cut the arena up for about ten seconds; he also charges a green ball that bursts into fragments.
- When he calls down spears, move away from where you are: that is where they will land.
