Can we get a freeplay mode? with more and more enemies, harder and harder, with the chance to buy units every 5 waves or so? would be dope... also would be nice to hvae one more upgrade level like a t3 unit in each section.
Would love some sort of endless mode. or a tiered Campaign where you can play 20 waves w/ 5000 starting gold and breaks every 5 waves. This game has the potential to be endlessly replayable. Maybe something along the lines of the way Protectorate does it. Overall very fun 2 hour diversion :)
 "Royal Warfare"){kind=icon}
 "Cursed Treasure 2"){kind=icon}
 "Rebuild 2"){kind=icon}
Survival mode will be released in 2014, together with tier3 units and lots of other stuff.
