... OK, the game is old, but it's still being played by tons of people around the world.
SuperCheats member SPV999 has knocked up a huge mega guide to Twilight Princess.
It includes a complete walkthrough and stuff like heart piece location guide, poe guide and enemy and boss guide. It's fully illustrated with screenshots.
Thanks to SPV999 for a great job, and hope you guys enjoy the guide:
