Process Of Elimination

This is the first mission of the final phase.

Once again Max has to get from point to point without being detected.
How I hate these missions.
You only have 12 guards to take out in the first phase of this missoin.
After using stealth on the first 2 guards, I found out that the only way to take out the next 2 was with the X-5 gun.
After you take out all 12 guards you move on to phase 2, climb the ladder and you get to go into battle mode again.
Take out all those 3 guards (all 3 are tough so watch what you do), activate the switch, then go to the next switch.
Phase 3 is all battle once again and you gain access to the keycard. You have 4 guards (all tough) to battle.
Open the gate and gain access through the ventilation duct.
Then begin yet another battle, but this one with a twist, I don't recall how many guards but they keep coming when you run low.
I hope you have plenty of health or have learned how to minimize the lose of health against specops and red series
Follow the game to the end of the mission.

Once you complete this mission you add the following to your inventory: Health - 8
Walkie Talkie - 1
