wow…
Yep.
The Saw blades in ravenholm and the HL2 rocket launcher
Propane Gas Bottles + Gravity Gun + Zombie = YABBA MY ICING!!!
HL’s Glock. Firepower that’s accurate at a distance…
Gluon Gun. Simply because it makes everything WAY too easy.
The Snark. Throw it at your enemy, watch him get eaten alive. and when he’s dead, run like hell until you hear the snarks explode.
MA COCK 
Oh wait, I’v done that one.
Uhm,…the power of love?
Sniper Rifle. Because of its power and zoom feature.
its gotta be the shotgun or the crowbar i use both because there both epic.
- Shotgun
- Tau Cannon
- Gluon Gun
On Xen I liked to use a longjump+double shotgun blast combo 
Favorite weapons would be the shotgun and crossbow… depending if I want to be stealthy or not.
Running in that Office Complex large room full of vorts blasting them with the shotgun is great. Actually, killing anything with the shotgun is fun.
I’d definitely have to go with the Shotgun for HL2/ep1/ep2 but for HL1 I’d have to say the MP5 (running down a corridor pumping rounds into Vortigaunts is too much fun 
)
Paint cans.
Nothing like making your enemy look a little brighter.
^ winner
Engines.
They make crazylegs dance!
1.the crowbar(boredum+cheats=garg dieing by crowbar)
2.nuke aka every scatchl charge and trip mine you can carry placed around a glitched enemy it will eather blow the enemy up or crash the game it 50/50 so far.
Magnum. Pew Pew!
The Zero Point Energy Field Manipulator( Damn I feel so smart after saying that…) + anything it can pick up = Zombies QQ!!!
