I'm impressed. This is probably the most polished Early Access game I've ever played, and also one of the best-looking ones as well. Especially for an indie developer. The game is perfectly stable, crash-free, and runs smooth as silk on my PC. Was able to set my options and join an online match within seconds, no problems whatsoever. The game runs on Unreal Engine 4.
It has all of the settings you would expect from a proper PC game. World detail, shadow detail, light shafts, AF level, multiple forms of anti-aliasing, different framerate caps, V-sync, and FOV slider that can go well over 100. I'm playing it on the "Very High" preset with a few extra tweaks. I'm sure I can run it on "Ultra" just fine, but I haven't bothered trying yet. It's such a fast-moving game that there isn't much point in stopping to admire the pretty graphics (but it's a very pretty game anyway).
The menus are laid out well, the server browser is slick and functional, and - as I said - the whole game feels extremely polished.
Fans of Quake and Unreal Tournament will feel right at home here. The devs have been pretty straightforward about their resentment toward F2P games and microtransactions. There's no leveling, loadouts, XP, or any other "modern" FPS features. No sprinting, no ADS. Bunnyhopping is alive and well. The rocket launcher is the most devastating weapon in the game (as it should be), but it's not fast enough or explosive enough that it doesn't require skill.
The weapon spawn points actually have a timer floating above them to show when they will respawn. A clever feature that I have never seen in an arena shooter before.
The one little gripe I had is that I couldn't modify my settings during a match. Had to back out to the main menu to change my mouse sensitivity. A bit frustrating but something you'll only have to deal with once.
The other thing I should point out, is that there is, literally, only one map right now. But it's a very fun, polished, and well-designed map. Lots of branching paths without feeling too cramped. My understanding is that the developers are working on balance right now, and will release maps over time; the next map probably being sometime in early February.
Really glad I took the risk on this game. The people making it are obviously pretty passionate. If you're looking for classic deathmatch-style gameplay with a modern coat of paint, it's a must-have.
