Can't complete the game 100% (or don't want to) or/and don't want to use cheats (because your save will get corrupted)?. Then this CLEO script is for you, it adds a Rhino Tank and a Hydra Fighter in Ganton, next to Carl's house (as written, after beating the game 100%).
Installation: Just add it to the cleo folder and that's it.
Note: If you load your game, they will change their location.
