Hello my friend.
Now I am happy that you enjoyed my game! :D:D:D:D:D
You know how can be frustrating whenever someone tries to play your game but it constantly crashes on the player’s end.
I think I imagine what may be happenning.
The game is crashing sometimes whenever loading the map assets, the meshes. So I suspect it maybe something like out of memory.
It happens with me especially sometimes whenever I am with UDK Editor openned and many other softwares openned (especially google chrome which is a HUGE memory eater).
So, whenever you are going to play the game, please, close everything which you don’t need to have openned. I do this as a natural habit (I close everything which I don’t need directly by task manager).
About the game itself, no, it’s not that hard, it’s strategic. You need to take cover to kill enemies by manually crouching behind boxes, hiding behind walls, doors. Try to shoot directly on the enemies’ heads (to save ammo and kill them with one shoot).
Pay attention to the map itself, you will find some important items to accomplish the mission.
Cheers my friend.
