I finally did the last boss fight in Trepang2. It's a great game but bosses are not its strong suit. It was more one of those things where I got up to it, didn't finish it, and decided I'd get around to it later.

That being said, now the game is done I might got back and play the shit out of the regular levels again. I almost don't use the slo-mo and turning invisible is great. Instead of stealth until you're found, you go invisible so you can do constant guerilla tactics and pop in and out of stealth.
