I was testing some routes in the Research Lab level. When I reached the elevator room, I simply made a jump like any other, but magically I hit a false spot and fell to the floor below, skipping the entire cutscene where Hawk activates the elevator and makes it go down. After discovering this, I tried again to see if it was just by chance, and I really managed to do it again

Hello, everyone!

After spending about 2 hours trying to figure out what was happening with the glitch that gave me unlimited ammo in the Steel Mill level, right after I picked up a red keycard and a pistol, I’ve figured out how to trigger it. It might sound crazy, but I got it to work more than 5 times. So, let’s get to it:

To trigger this glitch, you need to reach the door shown in the video with only the knife in your inventory. NOTHING ELSE! Once inside the room, you need to eliminate the two enemies on the floor. After that, wait for the iron door to lift and for two more enemies to appear. At this point, you need to make the guy at the top of the room throw a grenade (important detail: he can't die from the grenade, and you can’t kill him either — the grenade just has to go somewhere harmless). After that, the iron door will open, and you’ll need to kill ONE enemy with a kick and the other with the SPECIAL attack. After that, pick up the red keycard first and then the weapon. When you exit the room, you’ll have unlimited ammo for a good amount of time!

To summarize, to make it work:

1. Enter the room with only the KNIFE in your inventory (I had 2 in the recording).
2. Kill the two enemies on the floor with kicks (just like in the video).
3. Make sure the grenade guy misses the grenade and doesn’t kill himself.
4. After the door opens, kill one enemy with a kick and the other with the special attack (preferably the special kick).
5. Pick up the red keycard first.
6. Lastly, grab the weapon.

NOTE: In the video, I broke a box that’s empty, but feel free to break it too – it won’t hurt!

At the end of the video, I left two failed attempts — one where the grenade guy didn’t throw the grenade, and another where I killed both enemies with the special attack.

I know it sounds crazy, but it worked lol.
