HOW DO U GET ALL OFF THE LEGACY WEPONS AT THE BEGINNING OF EVE OF EXTINCTION?????????????????????????????????????????

I'm not 100% sure what you're asking, but if you want to know how to get all the weapons at the very start of the game: It's impossible. To my knowledge, there's no way to start a file with all the Legecy weapons. There may be a gameshark code, but I wouldn't know.
Howevere, you MIGHT just be confused about it. When you start a new file after beating the game, your weapons will retain their levels from your previous file, along with their ley seeds. And you'll get a new weapon as well. The twin blades.

Do you mean when you have to go into the wherehouse in the beginning and you are left with only your bare hands to defend yourself? It's easy, you get the rod and the sword back after completing the area. Remember: If you have trouble, turn Eliel back on. She'll tell you what to do.

Hm. The same question is posed underneath this thread. It seems they just want some sort of cheat, maybe L1 + L2 + circle or a gameshark code. That's kind of sad, that they want a cheat on this game.

Lol its not that hard of a game why would you cheat beat it first then cheat but theres no cheats unless you use game shark or somthing.
