Well from what ive played of it so far (ive had it for 1 day and played a good 8-10 hours of it already) I am greatly enjoying it. Weapons are much like our ut99 ones with some better tweaking to some imo. You can wall run which is pretty cool and im starting to get the hang of it, and combo it with some weapons (also to use jump boots you double jump and you can do so many tricks with them, they are pretty op and much better imo). Only weapon I really don't like on it right now is the shock rifle it just seems really slow and sluggish compared to the UT99 one.
Not to many people are playing it right now since its still in pre alpha, but once the ball starts rolling I can see this game getting pretty popular. Why? Because its a mix of everything that has made ALL the Uts great. Although I haven't seen any vehicles in it yet, which would be awesome if they could introduce a gametype with vehicles in the future.
Also I did have lag in the beginning and it does happen from time to time just hopefully have everything set to low, and decrease your screen performance, it may be a bit blurry but it could help.
For only being in pre alpha im surpsied that ive enjoyed it as I have, and im sure that once it gets out, it will be much better.
