ok so i was finishing the battle of the dam for the legion on my hardcoe play through. im at the part when oliver comes out with all of the heavy ncr troops. since stimpaks and any other health boosters take time and dont do have that great of an effect, i get murdered every time. I tried setting up mines all over the place and they accidentally shoot them and it explodes in my face, i cannot run away fast enough. im low on ammo considering i just did the whole battle, and im basically stuck with a gun that does a damage of 30. On top of that, all of the mines they had setup i disarmed, then saved. But somehow after i die and re-load the game, the mines are back and I am unable to disarm them or shoot them, im guessing this is a bug. And my first play through was for the ncr, so i have no prior knowledge on how to defeat oliver. So, any suggestions or tips would be greatly appreciated, thanks!
