Cohort II, even sharing the original's subtitle, has to be the laziest sequel in the history of the computer games industry. Why? It is virtually identical with its predecessor.
Let's have a look at what changed. Apart from the new title screen (Wow!), that is. Two languages the game previously spoke are not supported anymore (feature regression…). There are some new battlefield types, one of which ("marsh") is effectively the same as "bridge" combined with "hills" and the rest ("downs", "undergrowth" and "forest") plays just like the previously available "hills" as well. Of course, none of these new battlefields look any good graphically.
