At last, I finished the remaking of my caves, with six maps overall (the sixth one being a big elevator shaft) it took me a long while to conclude these, more than half a year but it will pay off pretty well, anyway I want to show you a bit of it:
This is a picture of a huge cave-in in the fifth map, there is a door to the right that leads to a big elevator (the main entrance to the caves) but the elevator is currently somewhere else, so the player will have to call it from inside that house to the front, and wait for it to come, however as you can see a small HECU squad is taking position over there, the player will have to take them out in order to call the elevator safely, but thats not all, the player is noticed and reinforcements come to aid the previous squad, so basically you will have to fight an almost endless wave of soldiers until the elevator arrives eventually, I have tested and polished this scene as much as I could and all I can say is that at least in my opinion, it feels awesome and it can actually provide a challenge.
Another picture taken from a different position, special thanks to Boris for the tank to the left.
And this is the elevator shaft where the elevator will get stuck and the player will have to climb it manually
This map is still WIP
They are watching you!
