Haha I would love to make it hard as nails but unfortunately it might not be liked
I have edited the code to decrease the ammo available to the player for all weapons, and some weapons (such as the machine gun) have a smaller clip. I hope to have the player need to look for ammo more often!
I was hoping to have the atrium battle above get harder the longer you take, but the more marines that enter the arena, the more likely they are to get stuck on each other, or rappel onto each others heads haha. I considered explosions to clear the areas needed, but this is unfair for the player. I might just stick to good old waves. I have 26 maps now! I hope to finish after 30...
