Thank you. Glad you liked it. As I wrote to kodikos, there is much planned for the game and being seen in the next weeks and months. Great that you found the references!
Regarding the enemy AI, it could be better, of course, and I will extend it as one of the highest priorities. But ammunition is not a problem. You can get it at several places (for free - yet).
I would like to have more persons walking around but animations are performance killers so I used a more conservative number, to be on the safe side. But I found it nice to see a silhouette coming out of the fog, and wonder whether it's a human or a robot...
