Death IncarnateG 40

One thing I would highly recommend doing, especially if you're playing in the harder arena's, is to load up on Exploding Meat as well as gathering or buying as many of the materials to make them as you can before going in. If things start getting too chaotic (which they will especially in the hard and very hard arenas) and your being swarmed by enemies, throw some Exploding Meat close by and all the zombies will stop in their tracks and move towards the meat. After about 10 seconds, BOOM. I found this was the best way to avoid being attacked by an overwhelming amount of enemies and to kill multiple enemies at once. While playing the arenas you won't swap items from your overall inventory, you'll only have access to the weapons that you are carrying. This why I suggest loading up on the materials to make Exploding Meat because you will be able to create more if you run out. Each inventory slot can hold up to x30. I'd also recommend having a modified rifle or pistol on you and loading up on the materials to make the Rifle Ammo Blueprint or Pistol Ammo Blueprint, enemies are weaker in the arenas so a gun will take them down in 1 or a couple shots so this is another good way to pick off enemies from a distance so you aren't swarmed.
