Played a few rounds and, it felt like Unreal Tournament front start to finish. It has the same movement options, and many of the maps are reminiscent of UT2k3/4 and UT99. You could find similarities in the weapons but they are fairly diverse. They do do a lot of damage and I felt some where more OP than others. (I could have been the latency/ping).
Playing with a 200ms ping to a EU server is doable, but being a twitch shooter a lower ping is a must. Additionally you will get kicked from servers if your rank is too low. Which I find frustrating at times, got kicked 4/10 times while waiting for a map change.
