Ok my fellow gamers this achievement is called,
INTO THE FREY
You get this for completing the 10 missions in chapter 1.
Getting 3 stars is not required
, they all can be done on easy which is 1 star.
You can keep replaying missions once you complete them for the money or points
Replaying missions can be done by backing all the way out to the main menu.
Hold on to your money or points that why you can buy health, grenades, bazooka or intel. while playing the missions for 3 stars.
Just keep in mined that these items will not stay with you if you do not use them in the current mission you are playing.
So if you buy something use it or lose it at the end of that mission
If you vote NEGATIVE please comment why and will edit the solution to address any questions or concerns.
