First, I want to say that I am really enjoying the game. I really like the whole mechanics and missions. So, Devs, great job. One suggestion to make it slightly more fun....multiplayer. I understand the trouble with adding them into the main game. What could be cool is the multiplayer in the unlimited waves. You could set the stage in the Black Gate being overrun. That would be a lot of fun to play with my buddies. Thanks for the time.
