what does it come with i know it comes with weapons and armor and thats it but are they good?

yeah there's a lot you get, makes you a lot more powerful at the beginning of the game (in terms of weapons access, good armor etc).

this lists all the 'packs' (you'll get them all in the one DLC now)

Whether the pack is worth it or not depends on how you're looking at it. You're not going to be using anything in any of the packs at end-game, but compared to the crap Doc Mitchell gives you at the start of the game, it's amazing.

Its not just the weapons and armour which as swk3000 says are useful early on but won't be what you're using later on, you also get useful stuff like weapon repair kits that come in very handy

Ok thanks for the info also the armor is fine. I rely on clothes throughought every playthrough I do and only wear armor toward the very end of the game. Once again thanks for the info
