Panic Art Studios’ Hero Siege ($2.99) is a frantic dual-stick shooter that released late last year. That initial version was fun, but certainly rough around the edges. Panic Art worked diligently to iron out its issues with many updates over the course of the last six months or so, and what we ended up with was a dual-stick shooter that we enjoyed very much, but felt that there was “tons of potential for Hero Siege to be more than what it is." Well, according to a post from Panic Art in our forums, some of that potential will be realized with a beefy update heading to the game adding tons of new stuff, chief among them cross-platform multiplayer. Here’s a recent trailer dishing out all the details of the new update.

Hero Siege is currently available on Steam and PlayStation Network in addition to iOS and Android, and once the update hits, the online multiplayer will work cross-platform between all versions. The update is dubbed Karp of Doom and should be available in the Steam version of the game later this week, with mobile and PSN getting the update sometime in the near future. Also, some of the performance issues that have plagued the game since its release as a result of being made in the Game Maker Studio software have been fixed up, so it should be an even more solid release once the update hits. When we get word on when Karp of Doom will be hitting the iOS version of Hero Siege, we’ll let you know.
