(b40) Increased AIs (Assault on the Control Room)

Increased AIs in all encounters (same goes with marines) and modified some weapon projectiles. (READ ME.txt) has all the information you need to learn more about this modified campaign map.

STARTING_MISSION_GUIDE
You may experience some issues when starting the mission because you will encounter aggressive commander elites heading towards you as soon as you drop off from the pelican. In order to beat them, shoot rockets while moving backwards to a cover-like-structure area where they may not come towards you unless you are too close to them.

I have not tested this on Co-op but it maybe possible if both (your co-op partner) downloads this modified map and play it.
If it does work then its recommended to play with a buddy to experience more AIs battle.

HOW_TO_INSTALL
Always remember to make a backup before proceeding.

Go to <C:\Steam\steamapps\common\Halo The Master Chief Collection\halo1\original\build\maps>,
 (The location for this can be different depending on where you have installed MCC)
Copy/Move <Maps/b40.map> to Steam's installation of "Halo: MCC",
Done

! Note that this <MAY NOT WORK> on <WINDOWS EDITION> of MCC.
  This was tested on Steam's version of MCC and it works fine :).

DIFFICULTY_CHANGES
All difficulties <ARE THE SAME> however, the <LEGENDARY DIFFICULTY> has slightly increased AIs.
Legendary, Heroic & Normal are the same as Easy such as damage.
All difficulty has different attribute changes. Legendary is deadly
