Trophy Description - Reach the end-boss of any level using boost only.

Trophy Type - Bronze

To unlock this trophy all you have to do is use only your Boost to kill enemies. If you use Overdrive, Shoot, or Bomb it will negate the trophy. Dying and having an enemy killed as a result of the explosion will not count against you.

The easiest and undoubtedly fastest method for unlocking this trophy is in co-op. Have your partner kill all of the enemies any way he wants (Bombs, Overdrive, Shooting, etc.), while you only use boost. Despite the fact your partner is shooting the trophy will still unlock for you.

If you are unable to find a partner or prefer to do this solo, I suggest selecting Rookie difficulty and the Nemesis ship. Just tap L1 to destroy the enemies over and over rather than holding it down for long periods. If you hold it down you put it on cooldown and risk dying, rather than easily darting around killing things.
