i dont know how you guys didnt find all the guns useful.
I used every single weapon in both games. The grenades save a load of time and health when your low and hiding, knowing theres an ememy right around the corner. The tripmiens are also awsome when your running away and place one knowing whoever is chasing you is now going to die .
The hivehand too was useful, sometimes i just heard the enemies and used the hivehand to get them round corners, its so quick and easy .
Who says the AR2 alt fire isnt useful too? that thing owns! when i know theres a bunch of combines in a confined space shoot one of those things in and when you walk in its all nice and clean for you .
I just nessercerily had fun with all the weapons, all very useful in their own situtuations. Also i cant be bothered to quote who said it but the fact theres very little ammo for the AR2 was the whole point as it does own and wouldnt be as fun it you could use it as often as the smg, which otherwise i used the smg alot as ammo is so easy to find .
Oh and forgot someone said crowbar was useless?, what about headcrabs when they jump at you they always seem to just miss me and i cant get a good shot at them thats where the crowbar comes in handy and you frenzy until its dead lol.
