*SPOILERS* How do I defeat Mama?

[DoorStuck]

I've been having trouble with her. I keep slipping off the platforms into the abyss and I don't know how to drop her health quick.

If falling out of the arena is your problem, just spend some time getting used to moving around in it. Get to a point where you can traverse it easly, then open the tank.

As for the fight itself, use the tank in the middle to block any line of sight until you can attack. The SSG and riveter are some of the most useful, being able to chunk her health and to hit her from behind cover respectively.

If you're still having problems... idk, quicksave your way to victory? Come back later?

You can also just grab the key and RUN!

SHOT IT UNTILL IT DIES

Yeah, grab the friggin' key, or... When you want to do it LEGIT: WIth this "Fall out of the arena" ♥♥♥♥, Big Mama remembred me of XIII. In the end, were you fight Mongoose. This is alot times harder... Especially when you compare the difficult setting normal DUSK/normal XIII. But seriously, it's a good shooter. Try it out!

Riveter and line of sight = your best friends

[Discussions_Acc]

The crossbow shoots through walls.
The boss is already there before you flip the lever (or whatever it was) and start the fight.

Maybe you can combine those two information.

I've always used the soap for a 1 hit KO.

[Shockhammer]

Shoot it untill it dies/Soap.

in 100% for this level i usually grab the sword and use charged attacks, kills in about 5-7 charged stabs
