Gameplay

The first stretch of Duke Nukem: Critical Mass asks very little of you beyond the basics: move Duke across a 2D path, jump over trouble, and fire at aliens. That familiar side-scrolling shooter/platformer structure is the game’s clearest strength, because it gives you an immediate handle on what you are doing. If you wanted a compact, old-school Duke outing after the style of a run-and-gun platformer, there is at least a recognizable foundation here.

The complication is that the game does not entirely trust that foundation. Its levels are built in 3D, and the route can pan or shift its axis as Duke progresses. That adds some motion to the journey without abandoning the side-view format, but it also makes the game feel caught between a simple 2D shooter and a more ambitious action game.

First-person and third-person shooting sequences arrive as interruptions to the platforming. Variety is welcome in principle, especially in a short-form action game, but these changes make the experience feel less focused rather than more exciting. The best advice is to go in for the basic Duke shoot-and-jump loop, not for a polished blend of perspectives.

Graphics

Duke travels along 2D side-scrolling routes constructed from 3D environments, letting the camera pan across areas and occasionally follow a change in the direction of the path. The game also switches to first-person and behind-the-back views for certain shooting segments, so it is more visually restless than a strictly flat platformer.

Story

The story begins with the Earth Defense Forces sending people into the future through a time machine, only for every expedition to vanish. With contact lost, Duke is sent after them. It is a clean excuse to put him in another alien-infested version of Earth, and it gets him into action quickly.

Once there, Duke discovers that aliens have invaded again and are experimenting on Earth’s women. That is very much the broad, deliberately crude Duke Nukem setup: a crisis framed mainly as another reason for Duke to start blasting aliens.

Time travel gives the scenario a little more shape than a standard invasion plot, but it does not turn Critical Mass into a story-driven adventure. Come for the familiar character and the pulpy premise, not for a more involved sci-fi tale.

Overall Experience

Duke Nukem: Critical Mass has the ingredients for a serviceable handheld curiosity: a recognizable hero, a future-Earth alien invasion, and a side-scrolling action format that suits quick sessions. When it stays in that lane, you can see what it is reaching for.

Still, the game’s perspective changes and 3D detours do not add up to a consistently satisfying action game. Instead of sharpening the platforming and shooting, they leave the experience feeling scattered. The low score fits a game with a workable core but too little confidence in it.

Give it a chance only if you are already invested in Duke’s back catalog and can tolerate an uneven experiment on Nintendo DS. Everyone else is better served by a stronger entry in either the Duke Nukem or handheld action-platformer catalogs.
