We just received word direct from the Limbic Software PR department that their hip aerial zombie slayer Zombie Gunship [Free] is going to be free all weekend long. The sale just went into effect, so expect the typical pricing weirdness and “this item is being modified" errors for a bit while iTunes catches up.

This isn’t the first time the game has been free, but we liked it enough in our review that you really should snag it if you missed the freebie promotion last time around. (Or don’t already own it.) Since our initial look at the game, Limbic has dropped some great updates which have made the game even better.
