Episode 3 will probalby start right after EP2 with alyx mourning her dad… what else is there… you will proably wake up on the floor after DOG attacks the advisors and dog is comforting alyx while you wake up alyxs looks at you says something like “gordon, im glad your OK” she starts crying again then gets up agrily and says “Gordon, those combine bastards have killed my dad we must get the the borealus to stop them from teleporting”… then you get some time to free roam look for some spare ammo or a gun since like in the others you wont start with anything then fly off into the sky and …ect
if you wanna see what i think will happen after this go back a few pages i posed what i think will happen this episode, its pretty good but simple imo if valve were to use that they would prolly add some brain ninjas (brain ninjas are just like… i guess mind f$@ks to mess with your head) and some action
