Recently i've been playing the hell out of Fallout 3. It is actually suprisingly good - i didn't expect it to be this addicting - although i suppose itwas game of the year in 2008!
Long story short, i went to a few scary metro stations and found heaps of ammo. Then i went back to "Megaton" the nearest town and was suprised to see a stray dog there! It was called Dogmeat and it seemed happy enough to follow me around. Now he's my own massacre dog and whenever there's and enemy about - he takes no prisoners! He also acts as a sniffer dog and finds ammo, chems, weapons and all sorts for you!
And... best of all - he's practically invincible! Really! He can be set on fire, hit by a missile launcher, blown up by grenades and he can even take a mini-nuke and only loose 1 health-point!
So far i've killed... Radroaches, Giant Ants, Radscorpians, Fire Ants, Ghouls, Feral Ghouls, Glowing Ones, Yui Guans, Deathclaws, Humans, A Queen Fire Ant, Mole Rats, Centaurs, Protectrons, Robobrains, Members of the Brotherhood, Brahmins, Super Mutants and Mirelurks, Sentry Droids and Mark I, II, II and Mark IV turrets... phew!
It's really fun, but my karma is extremely low meaning that bounty hunters occasionally appear to try and kill me... they never live to tell the tale!
