The MAG beta program is getting one final, well-timed push before Zipper Interactive gears up to launch the impossibly oversized shooter. The game has officially moved onto Beta Phase 4 -- a shift which not only makes 6,000 changes within the game (including modifications to the skill tree and an increased level cap), but also makes the beta exclusively available to those who've pre-ordered the online FPS at GameStop. Yes, if you've been playing the beta using one of the other promotional access codes, you'll be shut out of the proceedings. However, as a side bonus, Zipper is now keeping the game's servers open all day, every day. That's right, you no longer need to sacrifice your nightly Murder, She Wrote viewings to adhere to the beta's odd schedule. Thanks, Zipper!
