Just out of curiosity: has anyone ever seen the Codex for the Angry Marines homebrew SM Chapter? I don't know very much at all about WH40K crunch, so I'm not sure if what's written in the Angry Marines codex is underpowered, overpowered, or balanced.

Link to the Codex is here. (NSFW: the Angry Marines Codex drops so many F-Bombs that a Basilisk batter would be proud.)
