How to unlock Chapter - The Arena?

The Arena is special content from the Special Editions. Which version are you playing: PC or XBox360?

PC. I've finished the game on Casual and Hard and unlocked all the achievements, except the last 4.

You don't unlock it, it should be in additional content. Under continue and chapter select.

The game is not installed on my pc, is a friend of mine. I looked in the game folder and there is a file Arena.hpk. But in the game menu does not appear to chapter Arena, the last chapter is the Sanctuary. You have to unlock all the achievements for the Arena appears in chapter menu? Or only if you are logged that appears to Arena? The internet in my town is very slow and not have as I play online decently. You could send a save with all the achievements unlocked for e-mail diocresio_babayera@hotmail.com?
.
Obs. The version of the game is 1.00.595

I don't have all achievements unlock yet.

Right, if you own the PC (or Steam) Special Edition (it carries a red box on the front cover and an aditional flyer inside the box telling you about the arena) you can find the Arena if you start a new game or load a saved state and choose "additional content" as dgerver already said. If you don't have the Special Edition, you don't have this aditional content and that option will not be shown.
