fun tower defence game !
Waste of time.
The campaign isn't anything special, but just doing randomly generated stages and surviving to the end is addictive enough on its own. Careful, it's very easy to lose track of time while playing this game.

The campaign feels like a solid, by-the-books, RTS game with art direction that stands the test of time. However, for me the highlight is the Survival mode that feels like a combination of RTS and Tower Defense. Building the best possible base, full of chokepoints and turrets, to survive the eventual "billion" zombie swam is thrilling and addictive.

The world feels dangerous, the stakes always feel real, and every successful defense or hard-earned victory feels meaningful. It is clear that a lot of care went into the design, balance, art, music, and overall experience. Crazy good.
