Gotta wonder if the game is selling strong. Multiplayer doesn't seem to have more than 4 games in any playlist at any time, but that only goes for weekday playtime. Maybe more people will be on this weekend.
Still, great deal. Tons of stuff to do for $40, and it's damn fun. Nothing like sneaking into a Siege mode target with a stealth pack and planting a few singularity bombs then walking away unseen.
