Single player is really hard. I spent about an hour getting a few checkpoints through one mission. It’s really not bad hard, though. It’s good, challenging hard. It’s great.

As is playing co-op over the Internet. I’ve done a few random elimination rounds with Ade now and this evening we tried the first mission of the co-op campaign. We didn’t manage it. Well, we did in the end, but only after I’d given us infinite lives. We really need to do it properly some time, though.
