Hey guys! In this video I'll be showing you the Sonic 3 and Knuckles Easter egg in Aliens: Colonial Marines. This is located in chapter 6 For "Bella" and is after the part where you drop down through some debris. Inside the locker next to the sentry gun, you will see three little balls that look like the special stages from Sonic 3 and Knuckles. Thanks for watching and don't forget to comment, rate, and subscribe!
