I'm probably one of Era's biggest Siege fans and I thought this looked thoroughly mid. It's a hard pass at $60. Maybe once it drops to $20 with a few content updates it'll be okay. I wasn't a huge fan of Outbreak during Operation Chimera either. It was a fun, brief novelty carried by Siege's rock-solid gunplay, but not much more. I read PC Gamer's impressions (the writer is a big Siege player, too) and I don't think he was very impressed. The destruction and gadgetry that makes Siege stand out don't seem to be great fits in a L4D-style game.
