Surprise! There’s brand new Mass Effect DLC available right now.

After dropping word about Pinnacle Station a few months back, BioWare hasn’t said peep about the new arena-themed combat DLC, which made a stealthy arrival onto the Xbox Live Marketplace just a few hours ago.

Priced at 400 points ($5), it unlocks 13 “combat scenarios” aboard what looks like a space Thunderdome. After the bite-sized Bring Down the Sky hit consoles almost a year an a half ago, unveiling new content for the original Mass Effect is surprising to say the least. Not that any of us are complaining.
