Pretty easy to get the achievement. Get to level 48 or so, then wait around with a slower mob until a laser powerup appears... grab it and you'll be set.
I would have liked to see a sound/music mute and volume cpntrols. The game seems to have extra loud music and sound effects.
This is just about identical to Momentum Missile Mayhem by the same author. Unfortunately, the creator makes excellent UI's, but terrible games.
The complexity of everything is just way overboard for something that should be pickup and play. At least I only need to remember 9 hotkeys and the abilities actually make sense this time around.
That's what killed Missile Mayhem for me was that I had to remember 10+ hotkeys strewn around the keyboard and several of the abilities were ambiguous or were so confusing to use that there's no reason to even have them in the game.
Slick looking game, now if only there was something worth sticking around for under the hood.
