I have put about 50 hours into the V21 stable now on my first play through on normal. I just encountered and cleared my first battle ship and dealt with the very annoying mind control/dread problems. I dont know who is doing the mind control though. In the battle ship I captured an invisible alien commander, I wasn't sure if it was a bug or if he is supposed to be invisible... is he the mind control guy?
My second battle against the enemy (base assault) where they can mind control is when I quit. It was my experienced team and between the mind control, dread, and lizard guys running around every other corner suicide-grenading me I couldn't make much head way. I tried putting away my weapons, running through normally, rushing, having my brave soldiers leave their guns out and other put thiers away. nothing seemed to work, It was a very frustrating experience, especially with my experienced team whos veterancy seemed only to make them better at killing each other. I hope the mind control is limited to line of sight or its harder to mind control veteran in the future versions because this wasn't very fun to me. Also it would be cool if the dread increased the closer you got to the mind control alien.
Besides that I found the game completely engaging and one of the best strategy games I have played in the last few years. There was a lot of back and forth and great comeback moments... I look forward to release.
Bugs I noticed
-Music often no longer plays when returning to map from mission
-Game has frozen 2 or 3 times when a soldier begins to shoot in overwatch, the gun sound over and over and cannot finish action.
-Early and mid game, game will freeze after playing about 6-7 hours.
-Late game, game will freeze after playing about 2-4 hours.
-On terror mission in city, 2 walls can be seen and shot through. (I tried taking a screen shot but print screen doesnt seem to work on game.)
-Shields disappear when no weapon in other hand.
-Lizard guys change from having armor to not having armor sometimes while running around. When throwing grenades they are larger and about half way through the animation shrink back down to normal size.
