Barriers have been added to prevent mantis entering buildings etc. due to the fact that invisible blockers don't work with mantises.

A further route has been added from the flooded corridoor where camo is found to the library room. 2 windows which can be entered through, once the pallets blocking them are destroyed, have also been added to this room.

Also the upper room where the central stronghold is found now has a large open window which can be entered via a man-cannon on a lower walkway.

Finally all stairs now are covered with projectile blockers to effect the bouncing of grenades and therefore the effectiveness of the plasma-nade turret.
