CastleStorm invading PC on July 29

After invading Xbox Live Arcade in May, Zen Studios has announced it's bringing CastleStorm to PC. It's some weird and fascinating blend of RTS, tower defense, Dota, and Angry Birds, where you build up a castle then must smash down your opponent's by deploying troops, rampaging around as a hero, and firing catapults.

As well as a single-player campaign, it has competitive and cooperative multiplayer. The PC edition has customisable controls and graphics options to fiddle with, the announcement says, and it'd be jolly disappointing if it didn't.

CastleStorm will cost $9.99 when it hits Steam on July 29, but pre-orders are only $8.99.

Here's a new trailer explaining how to build your own castle:
