Just thought I’d let you guys know that players can complete a Spartan Ops mission without really playing it to the finish which allows them to get easy achievements. This can be done by first choosing any specified mission or chapter before starting the game, the player then can immediately quit the game or whenever they choose and upon exiting the mission/chapter it is shown as being completed to that specified difficulty. As such I have discovered that this exploit enables players to get some of the Spartan Ops achievements such as those that require the completion of entire episodes, including those tied to specific difficulties. However this trick does not affect the achievement that requires players to enable all skulls per the Spartan Ops LASO achievement. I hope you can address this issue in the near future so as to ensure players play through the entirety of a game, Thanks.
