Trophy Description - Kill 100 enemies during Overdrive

Trophy Type - Silver

Overdrive is the R1 skill that each ship has. When used it slows down the game, makes you invulnerable, and launches a giant green laser out that instantly vaporizes anything in its path. After killing enough enemies and collecting the green particles the overdrive meter will fill. You can tell how full the meter is by looking at the green bar underneath your ship.

The most reliable method for unlocking this trophy is by using overdrive against the final boss on the Decima level. Once the boss takes enough damage it will replicate itself and create a grey cube, which is signaled by a flashing red square. When you see the square immediately with stop firing with RS, then use overdrive once the grey cube appears. The trophy will unlock once the overdrive comes to an end.
