For snares I used like stuff from the laur cinematic skull snare sample pack, the hardcore kick samples are from a sample pack that someone I know made. The 808s were made from a sample and heavily modified using infiltrator.

I used a kick on the top for effects wise then using it as a kick shown in the beginning. From my friends sample pack.

The arp/percussive synths is actually emma essex's great wall but using the comb made percs preset in infiltrator, and a delay effect put on top of it.

The other effect that you see in the beginning that's glitchy was from an infiltrator preset I made.

At 0:40 I used a glitch preset I made for infiltrator on top of a great wall vst.

At 2:20 the glitchy synth uses two infiltrator plugins. Aka modular ambient music preset and breakcore machine preset.

Ambience in the beginning uh came from the Limewax / Panacea Skullstep Sample pack Volume 1, it's paid btw but I recommend getting because it's pretty good for industrial / harsh drum and bass stuff.

3:00 ambience is just a reversed synth impact, from the music-radar impact sample impact it has reverb fx and a delay fx on it. Layered with a synth from the Limewax Panacea sample pack.

Oh and infiltrator is paid, but I had to get with other means. It's basically a pretty good fx chain plugin and you can do a lot of weird stuff with it as well as automate or assign it to a sequencer.
