There are a lot of new features that are getting tested here. Here are some of the bigger ones...
New A.I.
The robot guards have new A.I. that makes them react to the player's position. They will now hide behind walls and emerge to shoot as needed.
In this gif you can see two of the new features. Right at the beginning you can see the red damage circle when the player gets hit. Then, watch the behavior of the guard as it peeks out and takes a shot at our protagonist before retreating behind the wall...
Aim Issue
The crosshair for weapons was a bit off in previous versions. Actually, it was the trajectory of the projectiles that was off, but these have been addressed and should now aim straight for the center of the screen where the crosshair resides.
Damage Effect
The protagonist, when taking damage, will now show a growing red circle that starts from the direction in which the damage was taken. This should help identify the source of harm. Also, she will express her discomfort by saying "ouch."
Urchins
The outdoor "urchin" creatures can climb a bit better now, and have an improved attack sound effect.
Outdoor Performance
The frame-rate in the outdoor areas has been improved since the last default version.
Health and Ammo Drops
Previously, health and ammo that an enemy dropped had a good chance of falling through a floor or wall, making it unreachable. Now they should bounce off of the walls and should not pass through floors. With these drops, they are given out randomly, not every enemy will drop something, and it will not always be the same type or amount.
