Yeah, those Sonic fans are weird. They anthropomorphic characters. Crazy. We pony fans prefer our normal, brightly-colored ponies. Totally normal. ;-)
Guess I shouldn't have red the article. I had heard that the game ties back in with the main lore, but had been avoiding finding out how. My own fault, but it doesn't surprise me. I mean, there's a CGI movie coming out that has his team showing up at what looks like the same place, so...
Here's a thought! You can have the DLC be about a soldier, but don't have it be Chris! Have you play as one of the no-name, first day on the job guys that gets separated from the rest of the unit. A rehash of the first game? Yes, but think about it. Rookie soldier is now on his own, and while he's got the weapons, this is something completely out of his depth. How fun would it be to play someone who, on paper, should be able to tear these monsters apart, but when it's actually time, the monsters aren't going down like they should, or he freezes up, or...I don't know. I just think it'd be fun to play as random guy number six, instead of one of the unkillable characters.
