Saw a vid of this the other day on Reddit, looked exactly like someone trying to do something I'd been hoping for a while. I'd also been thinking it did look like it needed melee though.
But £25 on steam for the game, with no Amazon sale over here. Not willing to risk the cash on an alpha mod that presumably requires rather a lot of resources to power servers despite no income. And all of that on a BIS game - a dev I generally associate with games as buggy as they are ambitious.
