Half-way through the game Duke enters the alien hive where all the kidnapped women are held and impregnated (raped) by aliens. He finds the twins that give him a blowjob in the beginning of the game and they apologize for being fat. (apologize for being pregnant (apologize for being raped)) Duke tells them they are fucked (by aliens). Then they explode into gibs and baby octabrains.

The first part of the game is full of misogynistic, dumb, juvenile shit like that. Women prance around with their breasts in full view all over the place. Faggs cigarettes. Absolutely every brand name or name or actually any text at all in the entire game is some sort of pun on either shit, piss or genitals. In the alien hive there are for no reason clusters of breasts hanging from the wall, you can slap these and gain a health bonus. After defeating the alien hive queen (who also has three giant tits) Duke passes out. Then begins a dream sequence where Duke is in a strip club and has to go on a fetch quest to find popcorn, condoms and a dildo. It comes completely out of nowhere, I wish I was making this up.
Everything about the Duke character has become unlikeable trash. He used to be some goofy muscle dude who spouted lame one-liners and gave cash to strippers. Now he's some gross ego-trip of a teenage, objectivist fantasy; Endlessly narcissistic, everyone in the game world adores him and literally wants to suck his cock. He just comes off as such an amazingly repulsive person.
Then the actual game:
Two weapon limit is straight out dumb. It is only there for consoles that easily could have gotten around it with some other weapon selection system.
The vehicle sections are passable, but could have used a lot more polish. The turret scenarios are boring and should have been removed.
Regenerating health is very boring and leads to a lot of just sitting behind cover when you really want to just run up to some monster and shoot it in the face.
But you know?
Besides all this shit?
I think the gameplay was actually good. It is old-school. You circle-strafe aliens and kill them. The weapons are good. (Except the shrinkray and freezer and a lack of ammo at times.)
Enemy variety is good, and only one of them (pig cops) have a hitscan weapon. That's right, you can dodge incoming projectiles! It owns!
There are a couple of underwater levels! That is awesome!
Some of the leveldesign is interesting. Some. Not all.
There are the cool levels where you are shrunken and you get to run around fighting on shelves and stuff, like those gimmick Q3A levels someone made.
There are jumping puzzles. I know I am in the minority, but I love jumping puzzles.
Some areas look really good. (Others look really bad, but not offensively so.)
I took a bunch of screenshots and annotated them while playing: http://steamcommunity.com/id/czg/screenshots/?tab=&showdate=0&filter=shortcut_32790
I played this on a PC with every setting on max, post-processing OFF (because it looks like shit, though I usually love stuff like that).
Installed it on an SSD, so load times were 3-4 secs per level, I hear consoles have really bad load times, upwards of 40-50 secs.
So in conclusion, is this a good game?
It starts horrible, gets better as it goes but keeps inserting amazingly bad low points throughout, the ending sucks, and the subject matter of the game is horrific garbage that no reasonable person above the age of 13 would enjoy.
It is a terrible game. Nobody should spend money on this.
Everybody should play it though... so please go ahead and warez it.
