I can type up the walkthrough that's in the book... it's basically a guide that walks you through the scenario if you DON'T have the expansion packs. I found it very helpful because it tells you what you should be doing at certain stars. It even tells you what kinda exhibits to build with what animals in them (multispecies exhibits are best!) It explains even how to START this scenario, and without a good start, you wont succeed.
If you people need any more help, you can email me. I've beat every scenario in the game, plus the ones from all the expansion packs, and I've unlocked everything there is to unlock.
and btw. using cheats to win really isn't winning now is it. You shouldn't need it!
