Considering that the game twenty years ago, Cannon Fodder manages to still look very nice. Viewed from a top down perspective, the environments look good, especially the more arid scenery from latter in the game. Even though the environments differ considerably from each other, there aren't all that many different kinds to begin with. 
Of course Cannon Fodder does look dated but what do you expect? Luckily, this doesn't harm the game. Like the visuals of titles such as Super Mario Bros, those of Cannon Fodder still have a great deal of charm.
The only real issue affecting the gameplay is that, compared with the PC and Amiga versions, the visuals are a little less sharp which does make some of the action a little hard to follow. Spotting traps for example.
Cannon Fodder is a simple game to play. The player controls a squad of between one and six soldiers. These soldiers are controlled as one single unit, though It is possible to split the squad up, in order to provide covering fire or lying down an ambush.

Most of the missions and their individual stages revolve around killing every enemy soldier or destroying their buildings. It usually comes down to doing both. A typical mission involves clearing a map of any enemy soldiers present. New soldiers can emerge from several small cabins so it becomes essential to demolish these buildings whether it is part of the objective or not.
During the course of the game other elements are also introduced such as vehicles, traps, wildlife and natives. This does add some variation but the gameplay never really changes all that much. Seeing that Cannon Fodder about twenty-four levels, neither a short game nor a walkover, it is a good thing that progress can be saved after each mission through the use of passwords.
