SpeedRacer and I were talking about having one of our own non-Destiny DBO nights, and "Rocket League" and "Tomb Raider" were suggestions, but I figure that Helldivers would probably be a great thing to stream and play together.

Definitely an underrated gem, the game is a lot of what I'd have loved to see in an ODST game:

You pick a mission, pick your dropzone, pick your loadouts (Each teammate can either play a specific role, such as medic, Heavy, Tracker, etc., or a run as a combination of many different skills), and then you do your best to survive the mission.

You gotta be careful, though; friendly fire is always on... Even when you're just joining a game, as I found out the very first time that I tried the matchmaking:

What say you folks to a night of diving feet first into Hell? Or Rocket Leaguing?
