Fantastic!

It seemed a bit too hyper for me, but I still enjoyed it. It was simple, yet I could detect some serious sinister vibes, which gives it an interesting twist. I've not heard of Sarin gas, but I'm going to believe Xecaria and agree on that note.

Great concept

I do like this idea. Sarin gas is highly toxic and there are rumors that the U.S. Government is experimenting with it in the aid of mind control. So you can hear the intention of that in the song.
If you don't know what Sarin is, the track is great for an industrial purpose.
The song is longer than most, yet there is enough variety to keep it from getting too repetitive. But listening to whole thing was kind of hard for some reason.
Good constuction.

Pumps nicely!

Only problem is the Arp that comes in around 2:30... not the arp itself, rather its' melody. Otherwise great job!
