This is a short video, that shows you how to get one of the archievements to get the Recon armor, you need to get 3 more to get recon armor, but this is the 1st step for getting it.
All the skulls are hidden in forge mode, so it makes it so easy to get them in no time, also, you need to download the 3 mythical maps of halo, otherwise you wont be able to do this.
Alot of people have been asking about this, so why not sharing it with the world:
The 1st scenario is sandbox, there you need to look for the exact location of the skull, grab a bubble shield and then evade all the lasers, after you are close to the wall, you drop the bubble shield to protect yourself from the lasers.
Then other scenarios are easy to get, you just need to convert into the oracle to get them, you just need to find the exact place and then follow the video path.
Also, another archievement is 7 on 7 you have to enter a matchmaking playlist with exactly 7EXP on the 7th of the month.
Well i hope this article helps you to get recon armor in halo, alot of people will envy you and you can show off with your friends, just remember i am just giving you 2 vidmasters, you will need to figure out the other ones.
