Bringing back the Amazon Preorder Bonus topic:

I taught there was only one code and one pack, but they were two!

If you've preordered MHST from Amazon you would get a second set of monsters: Ice Rathalos, Thunder Brachydios, Fire Lagiacrus and Water Qurupeco!

Also, the bonus codes were valid for older preorders and works both in NA and EU!
