Showroom androids - it’s way easy even on nightmare
Someone posted the showroom androids earlier. I commented that there’s somewhere you can stand where the androids don’t even see you as they enter. Their movement patterns are extremely predictable even on nightmare; nothing like the Xeno. I guess folks didn’t believe me as I even got downvoted. Well, as promised, here’s the video. This one is nightmare just to show you it works always, on every difficulty level. Be willing to sacrifice an EMP and a couple Molotovs. If you’re quick, you could probably skip the EMP.
The key is you have to wait for all six of them to enter the room and briefly congregate in the middle before you Molotov them, or you run the easy risk of missing one or two still straggling in.
