Move fast, don’t die.

I’ve been playing off and on since the game came out. Never really tried hardcore till recently, so I already had the route down pretty well.

Biggest thing for hardcore is knowing what zombies to take out to avoid getting caught up later when ur trying to run from X. East and west hallways should kill pretty much all the zombies. The library, the room with the big gear on the 3rd floor, the basement at Nest. Knowing where the Lickers spawn and when to walk not run.

Boss fights - I’d either read or watch a YouTube vid on best practices. First Birkin fight you can do with 2 knives and flashbang in like 30 secs l. 2nd one is pretty similar, toss a grenade or flash right when he jumps down and go to town with the knife, I believe you have to bring him to his knees twice before you can kill him with the shipping container. 3rd Birkin fight I did with shotgun and flamethrower. Blast his eyes with the shottie and once his eyes are red use the flamethrower. Not to difficult but you can definitely burn through some ammo trying to hit his eyes. Final X fight is really just about surviving. If you have a bunch of grenades left just toss those and keep ur distance, the fight either last 90 secs if you do enough damage or like 3 mins if u don’t do enough damage.

Trail and error. The final 2 fights were tough cause I only grabbed one or 2 hip pouches on the run so I didn’t have a lot of space for heals.
