The first of two planned packs downloadable content for the rather excellent Orcs Must Die! will be released on Steam for $2.49 on October 25th.
This Artifacts of Power pack will give you four new items, including life-draining Vampiric Gauntlets, the Alchemist's Satchel that lets you throw acid bomb grenades, a ceiling-mounted Shock Zapper trap that shocks and zaps, and the Floor Schorcher trap that throws orcs to one side and barbeques them on the other. The latter two traps can be upgraded, of course, with those excess skulls you may have gathered by now.
This DLC is for the Steam version and Xbox Live Arcade players will probably have to wait a bit as Robot Entertainment has nothing to announce on that front yet. $2.49 is not a bad deal considering the way you use different items for replayability in Orcs Must Die!, although I can't help but wonder how this will affect players who aim for the top leaderboard scores if they don't want to buy it. Hopefully the balancing won't affect whether you have the DLC or not.
