It's buggy but the concept is there.
Empty - No npc, no people were playing (will get better with time)
Couldn't get into the only two taxi's I found near spawn, despite the instructions to press E to use/enter.
some Objects (signs) were flickery (will be fixed I'm sure).
But singleplayer wise there's nothing to do but run and shoot and look around the empty map. Maybe if the driving worked for me it would be far more fun
