So many bugs that it is borderline unplayable!
On mission 2 of the main campaign and some of my experiences include:
Multiple game crashes
Car flipping on invisible things at 2mph!
Floating people in the road
Cars half stuck in the road
Tips stuck on my screen
Side missions not completing
Unable to come out of crouch
NPC clipping through walls
.... and plenty more... you had 8 years and release it in this state!!! Reminds me of Duke Nukem!
