There is no Halo 4, and will be none, however...
I think you are referring to Halo 3: ODST. If that is the case, then you can acquire recon armor by completing all of the Vidmaster Challenges in both Halo 3, and Halo 3:ODST.
Halo Recon probably because Bungie said there wouldn't be a Halo 4.
halo recon does not exist.
There is HALO 3 O.D.S.T (recon) and a new game called halo reach.
lol. Their is no "halo recon" its halo reach hope i helped XD
There isn't going to be a Halo 4. Halo wars is coming out and I heard somewhere about a game called Halo 3 Recon.
i think halo odst(recon) because I'm a major halo fan but left 4 dead is also pretty good but it gets boring
the recon helmet for halo 3 is unlocked by completing all of the vidmaster challenges in halo 3 and halo odst
you have to work for bungie to get recon
Lucky for you, there is now a way to easily unlock recon armor. There are a few steps you must complete to unlock Recon armor in Halo 3. 1. Buy Halo 3: ODST 2. Create a bungie account. 3. Complete the vidmaster achievements on Halo 3 and Halo 3: ODST. There are 7 in all. 4. Under your account preferences, click Unlock Recon. You should now have recon armor. RUB IT IN THEIR FACES!!!
To unlock Recon armor in Halo 3, you originally had to beat all of the VidMaster achievments, but the armor is now available to all players. To unlock the recon armor in Halo: Reach you had to pre-order the game and you would get a long (25 character) code for the recon armor DLC. To unlock the recon armor in Halo 4, you had to either pre-order the game or simply buy the armor with your in-game credits.
i believe you need to be around the lines between Lt. Colonel and General
Halo: Recon
