Cliff Bleszenski did pretty well with the Gears of War series, but his try at his own studios didn't turn out as well. Lawbreakers fell hard and fast and their latest entry in the Battle Royale genre, Radical Heights, wasn't enough to turn the tide.
With that, Cliff is calling it quits. He's going to take a break from video games, but let's hope he doesn't stay away too long. His studio did last four years, which isn't all too bad if you think about it.
Good luck Cliff and I'm sure you'll be back sooner than later.
