The most important difference we noticed? The build of Dark Void we just played featured a helmetless Will, so perhaps it's time to cut out all the "toasterhead" jabs. Dude's got feelings, too.
The gameplay reaches levels of freshness few games are able to tap into.
We also got a chance to check out an early level in the game -- a level that occurs before Will gains his oft-lauded flight capabilities. When you first acquire the jetpack, you're only able to do a simple double-jump and hover. While you're floating, enemies on the ground have a hard time hitting you. Said enemies also have a proclivity for hiding effectively behind cover -- sometimes, the best strategy was to rocket upwards from behind your own cover, and pick off enemies as you slowly descend.
Mixing that gameplay mechanic with the standard cover-based gameplay we've come to expect from third-person action titles helps to keep things really fresh. When you finally gain the ability to fly, and some of your adversaries become similarly airborne, the gameplay reaches levels of freshness few games are able to tap into.
Our opinion remains unchanged. We love what we've seen from Dark Void.
