How to unlock the Stalking Horse achievement in RISK - Definitive Guide
Set up a 2 human game. If you don't go 2nd quit and try again. Once you are the second turn you can just steam roll the other color until you win.
Just play a local or online game with just 2 players. If it is the other player who is allowed to go first, you will win the achievement if you win the game. Not hard at all. You can play against yourself locally with just 1 controller.
