Short summary of what "leaks" there are about 4.0 and what things are confirmed already by Ssnake
- 3D crews on all main vehicles and to most others - Eventually to all vehicles where crew would be visible. Damaged crew member will simply disappear. Exposed crew members can be sniped. If hit box will get over 70 joule hit, it will damage crew member
- Weather modeling. Now you can actually see rain of water and snow. - weather will affect visibility and thermal imager
- Night sky, you can see milky-way and starry sky that you can use for navigation.
- Working suspension modeling on vehicles (Not epic, but suspension movement will be visible. It wasn't intentional but a good coincidence. Win win)
- Better terrain bumpiness modeling, Troops will no longer sink into terrain, but actually hide behind visible bumps. (density of trees and objects doesn't change - just the ground bumpiness will come visible.)
- Roads will be significantly better leveled, and if I have understood correctly will be slightly raised up from rest of terrain. (Does this apply as well houses is yet mystery.)
- Additional vehicles including Russian transport helicopters from Mi-8 family, possibly able to carry supplies as well. (Some are armed with rocked pods)
- New IFV serie of TAM family as seen on the video. Interiors are not modeled, likely will be playable.
- Claymore mines and concertina wires can now be applied on mission editor. Concertina wire will have likely hood to damage tanks tracks. Can be breached with plows.
