Duke offers a plethora of both conventional and unconventional weaponry - the standard FPS fare of pistols, shotguns and rocket launchers are here, present and correct, but they're joined by novelties such as the freeze ray, shrinker, devastator and of course, the mighty boot. The enemies are varied and fun to fight, just don't expect particularly advanced AI from them.
What holds Duke back a bit is his often confusing level design. I was lucky enough to get through 'The Abyss' with minimal fuss this time around, but previous times I've been lost forever. The level design is hardly intuitive, but its certainly memorable all the same. You might find yourself reaching for a guide from time to time though.
Be it a nostalgia trip or simple curiosity, you need this game in your collection.
