Well….. at least the Normal Difficulty Campaign… not the Realistic Difficulty Campaign. So by beating the Campaign I unlocked the following achievements; Tough Hombre (30 Points), High Roller (30 Points), High Climber (30 Points), Street Cleaner (30 Points), Hell Hound (30 Points), Dam Buster (30 Points). However while obtaining the Campaign Achievements I also acquired the “Equipment Specialist” Achievement by doing the following… To avoid losing my Frag Grenades or Incendiary bombs what I would do when I came to an Outfitting Box I’d switch through each item once. Then kill myself then go back to the Outfitting Box and replace it with something I didn’t use yet. By going through each of them once I unlocked the Achievement. Because, the Achievement states… “Used all Gadgets at least once in single player Story“.
