it's an arena deathmatch first-person shooter game, currently in a pre-alpha stage of development. the developers have a ton of industry experience and are themselves avid gamers. here's their kickstarter trailer!

seem a lot like quake to you?
it is a lot like quake. one of the developers used to also develop cpma - a hardcore mod for quake 3 which made the game even more fun than vanilla q3 (of course that's subjective; it made the game a whole lot faster and the movement more interesting, which are two big plusses from me).
the reflex developers took cpma's gameplay as a base from which to work and built an entirely new engine for it in their spare time - all three also work fulltime jobs, and they have been spending what time they weren't using to sleep or make money working on this for the last 18 months.
so why play this when you could play quake or any of its innumerable mods?
- the fast-paced arena fps genre has been slowly dying for several years now. there's a small playerbase spread over far too many mods of quake, and this game has the potential to unite the majority of these players
- ease of use! a major problem with quake and its various mods has been that it's just too difficult to get into. the developers recognize this and plan on spending a lot of time on making the game accessible and creating high quality built-in tutorials
- in-game multiplayer map editing. you can make and simultaneously (by yourself or with friends) playtest maps. i don't think i need to explain why this is awesome :)
- in-game replay editing. fragmovies are ez
- dedicated servers and lan support
- high performance and responsive input (targeting 120fps with 1000hz input sampling)
- awesome spectator features. multiview, casting overlays, on-screen live statistics, spectator vs spectator interaction
- steamworks integration - friends, achievements, VoIP, player invites + more
- bots. one of the developers has decades of experience with ai and has the very ambitious goal of creating the best ai ever seen in an fps game. bots will use the tricks, stats, strategy and spam binds of real players
Here's a vid from a couple of months ago to give you an idea of where the game was at

note that official required specs haven't really been talked about yet, but a "reasonably modern" gpu will be able to run it at 120fps
