From the review: "Visually and aurally, Retro Evolved 2 is a significant step up from the original. It runs in full HD and the extra resolution is well spent on sharper ships and still-more extravagant particle effects that distort the arena nearly beyond recognition. At times it can be a little difficult to see everything that's going on, but when the going gets tough, Bizarre has built in unique sound cues to clue you in on the particulars. The soundtrack, too, is excellent, a clever concoction of pulse-pounding anthem and electronic ambience whose only real failing is that you'll have to be hella good to hear it all. Retro Evolved 2 more than matches up to the original - go back to it after a few rounds and you'll find the graphics muddy and the audio lacking by comparison.
In fact, in just about every respect, Bizarre has done a bang-up job of making Geometry Wars relevant again. Geometry Wars: Retro Evolved 2 looks, sounds and plays better than such a simple shooter should, by all rights; it's breathless, frenetic and addictive in all the right ways - and definitely not for the faint of heart. If the Xbox 360 is in any danger of flagging then Bizarre, at least, have got Microsoft's back, because what they're created in Retro Evolved 2 is singularly the best game on XBLA to date. Evidently, there's potential left to wring out of the old twin-stick shooter yet."
