Thanks.
Write in forum about "more optimized and more like cod" and in details, so I can understand what exactly you mean. Game already has similar to COD preset and game runs well even on low-end PC's.
There are few reasons why most maps are prototype (not completely finished).
1. Less details = faster loading and better performance.
2. Smaller download size. If all maps will be detailed, then you will have to download 4+ GB and 10+ GB on disk.
3. I don't have 3d artists in team. I am making this game alone and it will take 3+ months just to redo and finish all maps.
4. I personally prefer clean look of prototype maps. Easy to spot enemies, not like in some AAA games, where it's very hard to spot/see enemies.
