CastleStorm – Free to Siege is a free-to-play game which doesn’t shove micro-transactions in your face but doesn’t shy away from them either. The game is simple and fun to play.
You start off the game playing the Kingdom Quest campaign, where after years of peace the calm is threatened when the vikings start mysteriously attacking again. Luckily you play the hero who will work to defend the castle with a trusty bastilla, guide the troops into hand to hand combat against the vikings, as well as take to the battlefield yourself to get into the thick of things.
The game mashes up the genres of tower defense, action strategy and beat’em up with all three being used at once on occasion.
