From Halopedia, the Halo wiki
Momma's Boy is an Achievement in Halo Wars that is unlocked when the player receives a gold medal on any mission.
It is worth 5 Gamerscore.
- There are many ways to get this achievement, including playing any mission on co-op with a friend. This will undoubtedly make the mission go faster and will increase the chances of receiving a gold medal.
- If attempting to get certain campaign related achievements, such as Handy With Tools, the achievement will automatically unlock if not acquired previously.
- If neither of the above methods yield success, replaying the first mission and rushing through it while killing all enemies is a legitimate strategy as well.
