Typically, that's impossible unless you CHEAT. Sorry, I don't know the codes, but you can search them on Google or something. I tried before, just typing in the wrong codes can crash the game and if you type like 20 in a row it'll freeze. So, do a few every ten minutes or so.
See related links for all the perk and quest perk codes which you type inside the console box.
Only at the time you select them, you get the option to change your mind before you save and move on. The only other optin is to go back to a save before you selected the perks however this may involve you going back quite a long way for little reward.
You need to level up, as most have a level prerequisite, and some have stat prerequisites too.
I'm not sure its possible... sorry i wasnt that helpful :L
You get 4 perks when you unlock your classes at lvl 4. you get 3 perks for your weapon and 1 perk for your deathstreak.
Not in a normal game
You cant obtain any perks from a level-up after you reach 30th level. However, you can still get other perks from quests.
No and if it was even done. Microsoft would patch it...
To my knowledge it is NOT possible to have a deathclaw follower. Download more perks mod, search fallout 3 more perks then go console get player.addperk xx0036de old olney citizen. Pc only.
No. Perks are only ever granted on level up, and there is no shortcut to get the better perks apart from training the skills to the prerequisite level.
fallout 3 i presume? you cant "unlock it" as say you have to walk the walk, go to it by foot, there's a bridge to cross if you dont want to go through the river
Occasionally Fallout: New Vegas will freeze, but not as frequently as Fallout 3.
fallout 3 psp??????
There is no such place in fallout 3.
Fallout 3, Fallout 3: Game of The Year Edition, Fallout 3: Broken Steel/Operation Anchorage/Mothership Zeta/The Pit/Point Lookout
you have to level up by playing games online. More powerful perks are available the higher level you go
