Like previous mod(s) of Keen 4, this is limited to one level. However, "Torgopolis" more fully demonstrates what can be done with Keen 4 modding. The sprites and graphics are all original, and new concepts have been incorporated into this game. The story isn't much but it's definitely not a bad storyline. All in all, this was a nice mod, and I hope to see more Keen 4 mods of this caliber.
