In Half-Life 2, you can't customize Gordon Freeman with traditional RPG stats or skill trees, but you absolutely can optimize your weapon loadouts and playstyle approaches to dominate City 17 and beyond. Smart weapon management and tactical choices separate amateur resistance fighters from seasoned Combine crushers.

Understanding Half-Life 2's Weapon System
Half-Life 2 limits you to carrying specific weapon types simultaneously. You'll hold one melee weapon, two pistol-class weapons, two rifle-class weapons, and grenades. The Gravity Gun occupies its own slot and becomes your most versatile tool once you master HL2 physics puzzles.
Your inventory caps at 250 pistol rounds, 90 SMG rounds, 30 rifle rounds, 12 shotgun shells, 5 rockets, 30 crossbow bolts, and 3 grenades. These limitations force strategic thinking about weapon priorities and ammo conservation throughout your Half-Life 2 walkthrough.
The Meta Builds: Top 5 Loadout Strategies
1. The Physics Master (S-Tier)
Primary: Gravity Gun
Secondary: .357 Magnum
Support: Shotgun, SMG
This build turns you into a walking demolition crew. The Gravity Gun handles 70% of combat encounters while preserving precious ammunition. Launch saw blades at Combine soldiers for instant kills, chuck explosive barrels at groups, and manipulate environment objects to create cover.
The .357 Magnum serves as your precision instrument for distant targets and tough enemies like Hunters. One headshot drops most humanoid enemies, making it incredibly ammo-efficient at 6 rounds per kill maximum.
2. The Spray Commander (A-Tier)
Primary: SMG with grenade launcher
Secondary: Shotgun
Support: .357 Magnum, Gravity Gun
Perfect for players who love aggressive rushing tactics. The SMG's 45-round magazine lets you suppress multiple enemies while the under-barrel grenade launcher clears groups instantly. Each grenade deals 75 damage with splash effects.
The shotgun becomes your close-range problem solver, dropping zombies in one blast and stunning larger enemies. This build excels in tight corridor fights common throughout City 17.
3. The Precision Sniper (A-Tier)
Primary: Crossbow
Secondary: .357 Magnum
Support: Gravity Gun, SMG
Crossbow bolts pin enemies to walls and deal 50 damage on impact, 100 on headshots. The zoom scope makes this weapon deadly at long range, perfect for picking off Combine snipers and Civil Protection officers before they spot you.
This build requires patience and positioning but offers unmatched stealth capabilities. Crossbow bolts make no noise, letting you thin enemy ranks without triggering alerts.
4. The Balanced Veteran (B-Tier)
Primary: Shotgun
Secondary: .357 Magnum
Support: SMG, Gravity Gun
This setup handles every situation competently without excelling anywhere specific. The shotgun provides reliable close-range damage, the Magnum covers long-range precision, and the SMG fills medium-range gaps.
New players should start here to learn weapon strengths and weaknesses before committing to specialized builds.
5. The Explosive Anarchist (B-Tier)
Primary: RPG
Secondary: SMG with grenades
Support: Gravity Gun, .357 Magnum
Raw destructive power defines this build. RPG rockets deal 150 damage with massive splash radius, perfect for vehicle sections and group encounters. The weight limit of 3 rockets forces careful shot selection.
Combine this with thrown grenades and explosive barrels via Gravity Gun for maximum chaos. Environmental destruction opens new paths and eliminates cover advantages.
Situational Build Variations
Ravenholm Special: Gravity Gun + .357 Magnum only. Father Grigori's domain provides endless saw blades, gas tanks, and debris for throwing. This restriction actually makes the horror section more manageable by forcing creative problem-solving.
Vehicle Sections: Always carry the RPG when driving the airboat or buggy. Three rockets can destroy any Combine gunship with direct hits to the vulnerable belly plates.
Antlion Tunnels: Shotgun becomes king in underground sections. Close quarters make precision weapons less effective while shotgun spread reliably hits multiple antlions per blast.
Advanced Physics Tactics
The Gravity Gun transforms from novelty to necessity once you understand advanced techniques. Radiators deal 50 damage when thrown, instantly killing most enemies. Explosive barrels create 100-damage blast zones with 8-foot radius.
Pro tip: Combine energy balls can be caught and redirected back at their sources. This technique trivializes several boss encounters and saves tons of ammunition. Practice timing in safe areas before attempting under pressure.
Stacking objects creates impromptu cover and platforms for reaching hidden areas. Many sections have multiple solutions using physics manipulation rather than direct combat.
Achievement-Focused Builds
Several achievements require specific weapon restrictions or kill methods. "Where Cubbage Fears to Tread" demands completing Highway 17 without the car taking damage, making the RPG and precision weapons essential.
"Zombie Chopper" requires killing 1,000 zombies with the propeller trap in Ravenholm. This achievement naturally pairs with Gravity Gun mastery, as you'll need physics skills to funnel zombies effectively.
The "One Free Bullet" achievement gives you a single pistol shot for the entire game. This restriction makes the Gravity Gun and environmental kills mandatory for progression.

Mod Considerations
Popular Half-Life 2 mods like Synergy cooperative play and MMod weapon overhauls change optimal builds significantly. MMod adds weapon customization and new mechanics that favor different approaches than vanilla gameplay.
Episode mods often feature new enemies requiring adapted strategies. The Hunter-Chopper encounters in Lost Coast, for example, demand sustained RPG usage over hit-and-run tactics.
Before attempting modded content, master vanilla builds thoroughly. The foundation skills transfer directly while letting you appreciate mod improvements and changes.
Your Next Steps
Start with the Balanced Veteran build for your first playthrough. Focus on learning enemy behaviors and weapon effective ranges before experimenting with specialized approaches.
Practice Gravity Gun techniques in safe areas early in the game. The physics system rewards experimentation, and mastering object manipulation pays dividends throughout your entire Half-Life 2 walkthrough.
Once you've completed the main campaign, revisit challenging sections with different builds to discover new solutions and improve your tactical flexibility.
