Immediately after you start the game you will be standing in the train which is the vehicle you ride in for this rail shooter style game. You will see guns attached to the train by your hips, simply touch them and pull the triggers on your controller to pick them up which will unlock this easy achievement.
Please note that all achievements unlock once you fully exit the game.
