Brings back old memories and well worth the five bucks. Tough Achievements would be my only gripe. One problem is that the arcade game had a spinning knob for aiming and you could really move quick- not so with the 360 controller, which makes the extermination challenge difficult and the MCP challenges difficult, imo. But people are getting them, so maybe i'm lame.
Also, there should have been some sort of achievement for the tanks, especiallly the second or third level.
