You need to have completed Entropy: Zero 2 up to Chapter 2, Contact Aberration. Once you've gotten that far, start the chapter from the New Game menu.


Save the game once the cutscene ends and Bad Cop finishes loading his AR2. You might need to restart this a few times before getting it right.


Without moving, open the door of the crashed dropship. Your other weapons will fall out onto the floor beneath you. Move to the left side of the entrance and fall as far to the left as you can. If you do this right, you will only collect your MP7 and Grenade.


The Gauss Pistol uses the slot shared by the Crowbar and USP, so you need to avoid picking that up. The game will autosave when you collect the MP5K, so this will make it easy to retry from that point for either weapon.

The Crowbar and USP are backup weapons used by the Rebels. They typically appear if you have kicked one and disarmed him of his primary weapon. It's random which weapon appears, and since you can only pick one or the other, you won't be able to carry both in the same save file.


When you breach the first door in the level, a handful of rebels will be waiting for you. Kill the two on the left and kick the last rebel on the right. He will either draw a Crowbar or USP. You can kick him again to make him drop it, or you can just kill him and take it.


Once the weapon is on the ground, you will be able to pick it up like any other gun. It will occupy the first slot of your secondary weapons. Let's compare and contrast them...

You can make separate save files and collect one or the other from there. However, only one can be chosen per save. The Crowbar also uses the HEV Suit's arms from Half-Life 2. Additionally, you will lose the USP or Crowbar along with all of your weapons when you reach the Aperture Science Material Emancipation Grid.

You have a binary choice between a reliable melee weapon and a deadly pistol here. Let's see what they have to offer!


The Crowbar is your only melee weapon available during this stretch aside from kicking. You swing it quickly and deal light damage to enemies. It isn't the best choice against Rebels, especially armored ones. However, it kills Headcrabs quickly and smashes crates effectively! It's also good for saving ammo when fighting Zombies.


The USP Match works the same way as it did in Chapter 0. It's fairly powerful, shoots fast, and reloads at a decent speed. It also shares ammo with the MP5K, which can help or hinder you in combat. If you find plenty of 9mm rounds, the USP's accuracy makes it a deadly marksman's gun when combined with the zoom button!


The Gauss Pistol is arguably better than both...but I enjoy the USP's stopping power and the Crowbar's Headcrab-smashing prowess. Both can make fun additions to your arsenal until you reach that Emancipation Grid!

If any of the steps confused you, here's a video showcasing how to do the exploit!

I didn't find this glitch. It was mentioned in the notes of Entropy Zero 2's page on TV Tropes.[tvtropes.org] All credit goes to its writers for detailing the exploit! I just documented how to pull it off after experimenting with it on my end.


Thanks for reading! Hope you have fun using these weapons without turning on sv_cheats 1!
