My first thought was that the Leonidas-led Spartans would be fucked against the Halo-universe Spartans what with their better weapons and armor. My second thought was that OP didn't get the joke.
My third thought was, ugh, CTRL-ALT-DEL? I haven't read that since the string of miscarriage comics - not because I'm against writing about the subject of abortion/miscarriage, but because I think a guy who writes a comic about an immature, delusional gamer who makes up gaming holidays and builds wise-craking robots is not well equipped to handle serious subjects, not to mention that it was 100% irrelevant to his gaming comic.
