There is an air vent somewhere to the right. You shoot it and then you jump thru. This will lead to a very narrow passage way behind the scene and I'd recommend you to use pipe bombs if you have before jumping blindly because a bunch of Pigs are waiting for you there.

This and Worms were both new when I was visiting my family overseas...I came home and got em both. I love Duke though to this day

On my old x86 I liked to edit the user.con to allow a lot og pipebombs and tripbombs to be carried at once, start a new game on some level (usually it was E1L1), kill off all the monsters and then enter cheats to get god mode and then enter an all items cheat.
Then I was setting tripbombs and pipebombs all around. The nearest vicinity got really criss-crossed with laser beams, a literal explosive playground.

Was I enjoyed most about the game were Duke's lines... like:
''Nobody steals our chicks and lives''
'' S*** happens (after he steps on some)''
''It's time to kick a*s*s and chew bubblegum...and I'm all out of gum!''
'' Your a*s*s, your face, what's the difference?'' :D

personally I enjoy Postal dude's
Mmm,smells like chicken..after you burned somebody

Duke = A lazy bastard.

Seriously, most people like him, but how many lines did the developers rip from movies?

Well why not? It gives plenty of entertainment in some non-brutal moments. Must go kill, kill....

Because those are Bruce Campbell's quotes, along with some other B-grade actors no one cares about.

Cabel from Blood had nice quotes I think.

Did you expect a shoot em up game to have interesting, original and thoughtful phrases that the game makers came up with? That stuff can take a while to come up with, especially if they need to be catchy.

Not really, you just need a substandard notion of stupidity to accomplish it.
