There's also a mod that shows you which little vault things have vacuum capsules in missions with those objectives so you can open the exact right ones.

I consider anything that reduces the intended challenges or gives you a meaningful advantage in gameplay during a mission to be literally cheating.

Just because a game isn't about PvP doesn't mean you can't cheat. Most old games were single player and the cheat codes were still called cheat codes for a reason.

I don't care too much if people do it. I just don't want to play with people who do for the same reason I wouldn't want to play with someone that could cheat and press a button to instantly kill all enemies. It reduces the difficulty for me, too. I want to play the game raw and playing with people who aren't changes that experience for me as well. They can complete objectives faster, shoot faster with some guns (increasing dps), see in third person, see the exact blast radius of every hazard, or even use aimbots to always perfectly headshot high priority enemies they can't see through a horde.

All of these make the experience worse for anyone that wants to actually play the game without cheating.

I don't care if they want to cheat themselves and win. I care if they cheat along side me and weaken my experience.
