This is just a bad, bad game
There were no powerups aside from that "lazer" thing that periodically dropped that as far as I could tell had no purpose. Powerups add so much to a game and really irks me when people don't include them.
The ship models were far too big and it maneuvering turned out to be a nightmare. I took more damage from collision than anything else.
Shortly after the start of the first part of the game, the earth blows up. There is no warning and no explanation afterward. Just little earth shards in the background until you hit the asteroid field.
And about that freaking asteroid field; I've never been able to get past it. Every time I get the hyperspace warning I get creamed by an asteroid that is pretty much inescapable.
All in all, the sound is bad (the buzzer that goes off when that big ship pops in at the end of the first area sounds like you just recorded your drying machines' end cycle buzzer), the voice actors sound like they couldn't take this seriously if their life depended on it and well you know I could keep talking but this is just a bad bad game.
I do hope you read this review and not the other ones that are rating you 6 or 7 and saying the same thing but trying to be nice.
