Half-Life 2 is Valve's legendary FPS that redefined the genre through physics-based gameplay, environmental storytelling, and the Gravity Gun. Playing as Gordon Freeman in the dystopian City 17 under the Combine's alien occupation, you fight through varied environments using creative physics interactions alongside traditional gunplay. The Gravity Gun transforms every object into a weapon — sawblades, radiators, and explosive barrels become your arsenal. Twenty years after release, HL2's pacing, level design, and moment-to-moment gameplay remain a masterclass. The Episodes (1 and 2) continue the story with refined gameplay and one of gaming's most memorable endings.
Your choice of weapons defines your damage output and playstyle. This guide ranks every major option, explains what makes each one strong, and tells you which builds they pair best with.
Weapons Rankings
| Weapon | Tier | Best For | Notes |
|---|---|---|---|
| Gravity Gun | S | Physics Master, all playstyles | The defining weapon of Half-Life 2. |
| Crossbow | A | Conservationist, Run and Gun (long range) | A silent sniper weapon firing heated rebar bolts. |
| Pulse Rifle | A | Run and Gun | The Combine's standard assault rifle with a 30-round magazine and an alt-fire energy ball that disintegrates enemies. |
| RPG | B | Anti-vehicle encounters | Guided rocket launcher — the rocket follows your laser pointer. |
| Shotgun | B | Run and Gun (close range) | Double-barreled shotgun with single and double-fire modes. |
S-Tier: Gravity Gun
The defining weapon of Half-Life 2. Primary fire punts held objects at high speed; secondary fire attracts objects. Kills with physics objects don't use ammo, making it infinitely sustainable. The Super Gravity Gun in the Citadel is even more powerful.
| Attribute | Detail |

| Tier | S |
| Best For | Physics Master, all playstyles |
| Key Mechanic | gravity gun physics |
| Recommended Role | Run and Gun |
How to get it: Available from mid-game onward. See our walkthrough for the exact progression point.
Best builds using Gravity Gun: Pairs naturally with Run and Gun thanks to stat scaling synergies.
A-Tier: Crossbow
A silent sniper weapon firing heated rebar bolts. One-shot headshot kills Combine soldiers at any range. Bolts can be retrieved from kills (walk over the body). The scope provides precision aiming for long-range encounters.
| Attribute | Detail |
|---|---|
| Tier | A |
| Best For | Conservationist, Run and Gun (long range) |
| Key Mechanic | vehicle sequences |
| Recommended Role | Physics Master |
How to get it: Accessible in the early-to-mid game. Check our maps guide for the location.
Best builds using Crossbow: Pairs naturally with Physics Master thanks to stat scaling synergies.
A-Tier: Pulse Rifle
The Combine's standard assault rifle with a 30-round magazine and an alt-fire energy ball that disintegrates enemies. The energy ball bounces off walls, clearing rooms around corners. 3 energy balls max carry. The best mid-range weapon.

Weapons Progression Path
The order you should acquire weapons as you progress:
- Starting gear → Enough to clear City 17
- Crossbow → Your first real upgrade, available early
- Pulse Rifle → Mid-game upgrade with good scaling
- Gravity Gun → Best-in-slot, aim for this by late game
- Upgrade to max → The power spike from max upgrades is enormous
Weapons Tips
- Always upgrade your primary weapon before diversifying — one strong option beats three mediocre ones.
- Match your weapons to your build's stat priorities for maximum scaling.
- Sawblades launched with the Gravity Gun are the best weapon in Ravenholm. They slice through multiple zombies and can be retrieved from walls. Always carry a sawblade.
