The Ice City is a level in Keen 1, one of the few in the game that has an official name. It appears to be some sort of Martian city made out of ice blocks. It is populated mainly by robots (Tank Robots and Butler Robots), probably due to the freezing temperatures present in the polar caps (in this case, the northern one). The third Vorticon Guard that Keen encounters is in this level.
In this and other ice levels, such as the First and Second Ice Shrines and the Vorticon Commander's Castle, there are two kinds of slippery surfaces: white blocks, which are slippery when walked upon but Keen can still be controlled; and ice blocks, where Keen slides and loses control unless he jumps off the block.
If Keen falls in the room with the Vorticon Guard without the pogo he will not be able to backtrack. If Keen does not already have the red keycard this will result in him being unable to complete the level. If the Vorticon Guard has already been killed in this case, the player will be forced to quit out of the level or use the item cheat.
November Beta variations
The so called November Beta version of this level has some slight differences: The pizza below the bridge near the beginning is placed one tile further left above an ice tile.
