Below is an overview of the weapons you'll come across, as well as a few tips on how to use them effectively. 1. **Crowbar**: This is your starting melee weapon. Ideal for breaking crates, attacking headcrabs, and other close-quarter enemies. It does not require ammo. 2. **USP Match Pistol**: This is your first ranged weapon. It's moderately powerful and quite accurate, useful for headshots and picking off weaker enemies from a distance. 3. **.357 Magnum**: A powerful weapon with a slow rate of fire, the .357 is best used against powerful enemies or for precise shots. 4. **MP7 Sub-Machine Gun**: Lightweight and with a high rate of fire, the MP7 is effective for mowing down groups of light enemies. Its secondary fire mode launches powerful grenades. 5. **Combine Overwatch Standard Issue Pulse Rifle**: This is a versatile weapon, useful in many scenarios. It has a high rate of fire and the secondary fire shoots an energy orb that can eliminate multiple enemies at once. 6. **Shotgun**: An excellent weapon for close-quarters combat, the shotgun deals high damage to opponents. It can fire double shots as its secondary fire mode. 7. **Crossbow**: This long-range weapon one-shots most enemies and can pin them to walls. It makes a good stealth weapon, as it's silent and powerful. 8. **Rocket Launcher**: This weapon is mainly used for taking out large enemies and vehicles. It fires guided rockets, which you can steer by aiming your laser guide. 9. **Gravity Gun**: Unique to Half-Life, this allows you to pick up and throw objects, including explosive barrels and saw blades. Its upgraded version in later stages can also manipulate enemy soldiers. 10. **Grenades**: Useful for clearing out groups of enemies or accessing hidden areas. 11. **Pheropods (Bugbait)**: Only available in certain situations, this 'weapon' allows you to command antlions, providing a unique form of crowd control and distraction. Use each weapon's strengths to your advantage, understanding the enemy's weaknesses, your environment, and the best tactics for each battle will cause the most damage with the least risk. Like in most FPS games, aiming for the head usually deals higher damage. Don't be afraid to swap regularly between weapons as the situation demands – every weapon has its time and place. Remember to conserve ammo for powerful weapons when dealing with smaller enemies, but don't be afraid to use them when the situation calls for it. And always keep an eye on your surroundings for potential ammunition pick-ups or sources of environmental damage. Careful planning and strategic use of your arsenal will be key to surviving the hazards of "Half-Life 2".
