Ok so I wanted to make a place that has tips for this achievement. As many people seem to have gotten lost in the original, plus many new comers to the game. It doesn’t help that this level is probably the most annoying in the entire game.
I am by no means the best in the world, and hopefully those who do have that title will come across this and give their input. Anyway, I hope this helps anyone who tries to get this achievement. If there are any really good tips i will add onto the first page.
-Bandana skull can be a great asset in trying to get this achievement, I will not lie. It is possible without it though.
-i found the best weapon set to stick with was shotgun and assault rifle. Obviously you start with the assault rifle so no big. Search for a shotgun BEFORE you even go through that little tunnel at the beginning. Sometimes I don’t find it so i always just start all over until I get it and move on.
-if your using bandana, use and abuse your grenades! I can’t really stress that part enough. You’ll also have unlimited shotgun/ar ammo(my recommended load out) try to mostly spam grenades to kill everything. if the infectors(those little popcorn guys) get to close switch to AR. if the infected forms get to close switch to shotgun to clear them out and then continue spamming grenades. Cheap, yes, but effective.
-Learn the level! I can not really stress that part enough. If you barely know the level it probably wont happen. even if you just go through multiple times on easy to learn the level and where to go will really help you.
These are all i can think of off the top of my head. I hope that helps anyone who is going after it. And if any pro’s could leave input as well that would be good. i can even modify anything i already posted if better people have input.
Cheers! and happy running!
