I can see where a lot of the disappointment is coming from, but this game is actually very well built for what it is. Sure, it's an RTS and as such, a lot of people want to build up, but the pacing doesn't allow for that. The things you need to focus on, rather than building up, are being fast and poking at the enemy as much as possible. The last level for horde is simply this: create a squad at each base, grab both chests and use the money for two farms (maybe four farms, two mines/two farms, four mines) with which to poke the middle and top towers with. You just have to poke, poke, poke and build up while keeping a really heavy defense. It's a different sort of strategy, is all, no need to vote it down because you can't get it.
