Best used against: Combine soldiers, Combine elite, AntlionsДЄn assault rifle that is mostly used by Combine units, the Pulse Rifle handles much better than its other counterpart, the SMG.Alternate fire damage: Instant death (vaporization).During most of the game where you can use this item, you won't have any more than four Antlions at one time however, once in Nova Prospekt, expect the number to go way up. Alternate fire allows you to call them to you to defend yourself and regroup. Think of the them as shields and defenders for you, as you'll need them throughout the entire Nova Prospekt chapter. You'll have an infinite supply of Bugbait (and of course, an infinite supply of Antlions). That's right, The Pheropod is actually used to summon Antlions to attack any enemy in the vicinity of the Bugbait's range in other words, whereever you throw the Bugbait, they'll go there and attack anything in sight. However, Gordon uses it for a much better cause: to summon Antlions. Like the Gravity Gun, the Bugbait isn't really a weapon at all. Doors with windows, if positioned well when picked up, can act as shields without completely obstructing your view, as can radiators. Exploding items are useful, but remember that if it gets shot, it will blow up in your face. Oil drums (not the exploding kind) appear almost everywhere and have a lot of mass, although they obstruct your view more than some items. Cinder blocks are common in urban areas, and they fly well, don't obstruct your view much, and almost always kill instantly. in the event that you get the big, helicopter-like blade, it is useful, but not as good at a range. Bladed items usually kill in one shot, and saw blades fly fast and accurately. those things are Mass, size, how much it blocks your view, how well it flies, and special abilities such as blades or explosions. When choosing Gravity gun ammo, take a few things into consideration. You can distinguish this Gravity Gun by the blue hue it gives off instead of the normal orange one. Towards the end of the game, the Gravity Gun will be 'supercharged' so that it is more powerful and can pick up organic materials - the Gravity Gun can just about pick up anything that's not nailed down at that point. Objects too distant to be picked up outright can sometimes be pulled towards the user with secondary fire. Alternate fire uses a tractor beam that grasps objects (provided they are light enough), allowing them to be thrown with greater accuracy using primary fire, or dropped into place by pressing alternate fire again (this also works on manhacks and pulse rifle alt-fire shots). Primary fire projects a powerful beam of energy (often called a 'punt') at objects that knocks them away (this also works on headcrabs, ant lions, manhacks, and scanners). This is useful for all kinds of things, ranging from physics puzzles to actual combat. While technically not a weapon, the Gravity Gun allows you to pick stuff up and blast it away at high speed. Best used against: Obstacles, headcrabs (all types), zombies, Combine soldiers, manhacks, ant lions.

Max damage: Zero-Instant kill/Instant kill.
