I’m a big fan of Orcs Must Die! and its co-op sequel, Orcs Must Die! 2 (henceforth OMD2). I had a blast with OMD2 when it came out two months ago (as can probably be seen with the 5 out of 5 I gave it), but since then the “other twos” (other big titles that end with the number two) have sucked my attention away from this humorous, action-driven tower defense game. This week, however, I had the excuse of diving back into the game with the recently released “booster pack,” Family Ties .
