As usual in Serious Sam 3, the area in question is in serious plain sight. Acute players will have noticed this small green blinking item in The Power of The Underworld, roughly 400 kills into this serious level (after the serious infinite rocket storage).
It's seriously right under the crosshair. But how the hell would you get up there?
Climb on this seriously damaged wall further ahead, opposite the construction area leading to the next serious part of the map.
From there you'll see serious "secret keys" blinking in serious purple. Go back to the where that green item is located - the serious gates will now open for you.
You'll find a seriously long ladder on your left, before heading through the second gate. Climb it up, and, sure enough...
It's no crash to desktop, but it's a serious sight to behold, plus you get to have a peek on the following serious area. A very good peek I might add, since the green blinking item just around the corner is a serious sniper rifle. Unfortunately, it only comes with 5 serious shots and it appears it only can hold 10 anyway.
Remember to take the ladders on your way down, or you'll simply crash under your serious weight and suffer a seriously humiliating death. You can simply start taking the stairs with E, then jump off them and press E just before reaching the ground serious fast.
The disruptor's the correct tool to use here. Perhaps you're just not hitting the mine with it properly? Do you have the upgrade which lets you detonate the mines? You'll have to hold the detonate button down (R2 on the PS3) in order to get it to explode.
You get this upgrade from:
the cops in the Iceberg Lounge, during the side mission Remote Hideaway.

Looking at the Steam achievement list, it seems indeed the PC version of the game doesn't have the Catch achievement or equivalent.
