Its cheap, its quick, its Duke. Come get it, you can wait decades for DNF now.
MP does not feel like a good follow-up of the Duke Series, but is great to keep the flavor in your mouth, and its cheap price is another reason to do it.
The story is probably not the most original, but the places you visit are truly well done, and keep your attention.
Collecting nukes gives you more then extended max HP and ammo, but enable extra weapons, seemingly. And either way, the replay value is moderately, be it just for the sake of blowing up pig cop again.
Sometimes aiming can be frustrating, since shooting can only be done a cross-wise fashion, making the mouse nearly obsolete.
Shame, a 3D, Duke-ish version of a good oldie like Abuse would have been awesome. Anyone who knows Abuse knows what I'm talking about. (goldie oldies, huh?)
By 2009, the price of DN:MP will probably be next-to-nothing.
Good enough, I say, get yours if you can!
