Warhammer 40000: Boltgun: The ending [spoilers] 1080p60fps

Ok. Couple of things to point out. First, when I grabbed the Vortex Grenade in the container it didn't say 'secret found' because I found it earlier but couldn't pick it up because I was still carrying one from one of the the previous levels when I originally found it. Second, unless absolutely necessary, try to save your vortex grenades for boss battles. The amount of damage it does to bosses is insane as you can see when I used it on the sorcerer.
Thanks for watching.
Btw, my videos are usually at a nice resolution but RUclips defaults to a low quality so it runs smooth. You have to click on the gear icon in the corner of the video, select 'quality', then click on 'advanced' and select the resolution you like.
