Orcs Must Die! was a charming hybrid tower defense/third-person action game that challenged you to defend levels from hordes of bright green fodder monsters. We liked it a lot, giving it a score of 90 and an editor's choice award in our review.
The format is returning in fresh multiplayer free-to-play form under the slightly extended moniker Orcs Must Die! Unchained. This time you must "storm the opposing fortress together with your friends" while defending your own base, constructing a maze of traps to catch opponents out.
