I LOVE Orcs Must Die. It is the best tower defense series in the world to me. So when I found out this game is essentially a sci-fi clone of it, I was absolutely on board.

Like, 4-5 hours TOPS short (unless you 100% it). I feel like the devs were going to make it bigger and grander, but cut it short. Does it scratch t…
