Well, did a BT today and it's not bad. has quite a few quirks in it though and I can't seem to register on the beta forums to see if they've been reported or not.
For anyone who needs to know:
American Beta Server Times-
Tuesday and Thursday, 5:00pm-2:00am CST
Friday 5:00pm-Monday 2:00am CST
European Beta Server Times-
Monday and Wednesday, 5:00pm-2:00am BST
Friday 5:00pm-Monday 2:00am BST
(There just might be a pattern here.

Had to find these out from another source because the only place it tells you to look is on the beta forums, which you can't register on because of a known error. Frustrating.)
Anyways, Here's what I know (need to read that non-disclosure thingy better so I'm going to just tell buggs)
There are a few graphical bugs here and there, especially in the beginning (looks like a few areas have some major model probs at the beginning). Sometimes enemies are visible and walking in place, but are actually dead. Seen one die upside down on its head (I wish I had reinstalled fraps just so you could see that one

). The clan registrar is not active, so I haven't been able to see how the clan function works. You can't seem to dodge attacks either. No matter where I ran sometimes, I still got hit. They seem to have a lot of work to do, but it is fun (keeping in mind it is a beta). I have to run it on low graphics, so graphics are not so impressive, but you can customize your character. The choices are limited though so the likeliness of someone looking the same is high. I'll read the non-disclosure to see if I can go any further.
update: Welp, got my first major bug. I got stuck in a wall.

I was worried for a while cause where I got stuck, there was very little chance for me to die and respawn. After figuring out / brought up a console, I researched a little. Apparently TR is using elements of the City of Heroes engine. I typed in /stuck and viola, teleported to the nearest base. Thank god. I'm now at level 6 and chose the soldier path on tier 2. So far just doing missions. Seems very easy. I'm using the logos more often after finding out that they are more powerful than weapons at the moment (some weapons are level and skill restricted, so I can't use 'em) and ammo is unlimited until I get killed. Every time you kill an enemy, you gain adrenaline that fuels the logos. so you use logos to kill, it fills it right back up. Taking a break from the game to sleep. Server is shutting down Monday at 2:00 am.
