He's here!

Ah yes, Shrek in the big city and Serious Sam's co-worker.

The animations are very stiff, but nonetheless there's the strict minimum to be playable (TC, death anim, attack, spell).
I would gladly see this grow up.

i really hope he stocked up on bubble gum in advance this time.

Good looking model.
Would maybe give him some larger arm/shoulder muscles, to accommodate wc3's"epic" scale model proportions. Looking at the model from a far-away top-down view makes the arms small compared to, for example, how bulky orc grunts look in the game. Duke Nukem should look like a power-house muscle wise.

Animations wise, I think the gun should rest a bit longer in the air when attacking, pointing toward the target. Maybe add a muzzle flash.
The move animation is a bit stiff, but it works out for the model, because it makes him look like "he has no care" in the world.

Greetings to all, fixed animations: Attack, Walk, Walk Fast, Spell One, Death. I also changed the proportions and corrected the portrait.

Animations look too stiff for Duke, but looks like a fat chance to remake them and use the current ones for a terminator model

This looks VERY nice.
But first off, please add a collision shape, then "Decay Flesh" and "Decay Bone" animation (with the guts geoset) to fit accordingly with other Warcraft 3 units. Lastly, you can try to optimize the model further by fixing all of the issues detected by HIVE's Sanity Checker. (Using this tool might help: MDLX Optimizer)

A reduction of used polygons are also very welcome.

Hail to the king, baby!
I have long considered a Duke Nukem hero for my map, but obviously needed a model for it.
Animations aren't perfect, but it's decent enough

Nice! Please add Dissipate animation.
