Whilst visiting Mars to check on his pet Yorp Norp, who has taken chairmanship of the Yorp concil in order to elect a goverment to govern the freed Yorps, Keen picks up an odd signal on his Phototachyon Transciever, it appears to be coming from... everywhere?
Suddenly the world warps and Keen finds himself in... the same place? No... this is Mars, but... its different, subtle things have changed, such as the 50 foot tall statue of... a square? With a face? The statue is as thin as paper!
Suddenly a voice booms: Total dimensional collapse will begin in 3 hours, all quadroids report to central square, we will collapse the four dimensions of the 3D universe as soon as we can beak free from this pseudoverse into the 'real' 3Dverse; no one can stop us now!
The Quadroids are a race of 2 dimensional blue squares, they being 2D loathe our uncomprehensible 3D world and have decided to destroy it by collapsing the universe into a 0D dot! Keen must save the four dimensions.
PseudoMars is a warped and only semi-existant version of the more typical Mars Keen knows. As such, many things are simalar, and yet subtly different. For example, there are Yorps, but instead of Gargs a race known as the Sindri. Here, there being no Keen or Mort, the Vorticons have not landed.
Beware the Quadroids, being 2D, their edges are razor sharp and will cut Keen in half on contact! Also look out for their 3D attack drones.
Spoiler Warning! This shows the whole levels.
