Excellent tower defense-ish game! It's smooth, colorful, bloody, violent and pretty damn difficult at times. It's a lot like a single player Dungeon Defenders. Removing the multiplayer makes it easier to see whats going on, and allows for more creative thinking. Each new level, trap and ability you unlock will leave you thirsty for more and more Orc blood!
The traps are extremely divers and fun to experiment with. Some combos work better than others, and some strategies are easier for different people.
The pace of the game will keep you on your toes, and the learning curve is well balanced. With the constant addition of new enemies and new traps, your tactic will have to change throughout the game.
Its a good length for the content as well. If it was longer, it would feel drawn out or not leave enough room for omd2.
Over all, this game is a lot of fun and worth buying – on sale! I only stress that this is bought on sale because you can play all of the omd maps on omd2 – with or without a friend.http://steamcommunity.com/sharedfiles/filedetails/?id=7261685
