Any tips for the lost on Mars dlc. Be ready to muck around a bit but prepare to do something else after an hour or two, it gets PAINFULLY repetitive. If you never fancied Hurk in the base game I'd also recommend popping on a movie or music and silencing the dialogue. Stay off the sand, try to get the Obliteratorrr as it's the best weapon iirc.
After you get your first sniper, craft poison ammo for it. When you're attacking a base, a checkpoint, an AA site or any other places with groups of enemies, first, snipe any one of them with the poison ammo and they'll attack each other.
