It appears in the video that as soon as you leave the planet they'll countinue to go after you (and they appear to go fast). I wonder how long the lock will be for...... either way it's going to be annoying.
Huh, this looks like it will add a layer of tedium to replace the old one. *sigh* Bioware just can't get exploration right since ME1. All it needed was refinement, and it would have been fine. Or have a hybrid system. Like most of the exploring is done like ME2/3, but when a more important planet is found you land and use Mako/Hammerhead. There would be 2-3 planets like this, just to satisfy us people who want to drive the Mako. I loved that thing. I feel like Zaeed right now. The Mako was just so awesome. :'( http://www.youtube.com/watch?v=h9-dLzzQuVM When I was at the Normandy crash in ME2 I was very much tempted to place the statue at the Mako.

IGN got a space copy, or something. Anyways they're doing a review in pieces for it.

Guns ahoy, big spoilers here. Just what weapons there are. It's speculated it may or may not be complete. http://social.bioware.com/forum/1/topic/323/index/9028411

And the armors. http://social.bioware.com/forum/1/topic/323/index/9478281

Adept, Blood Dragon Armor, and that lovely M-5 Phalanx are how I'm going to roll. Carnifex has greater stopping power, but the DPS of the Phalanx allows it the sustainability of a rifle with less weight. Also I guess once in awhile the M-12 Locust can come too.
