Cyberia - Milestone 25

It would appear that you have gotten as much information as possible on the first level of the Cyberia Complex. You'll need to find a way down to the lower levels if you want all the answers you seek.

Grenade Ambush
Have Zak exit back out into the hallway and begin heading to the Conference Room. As you pass by the elevator, however, a Cartel soldier (possibly the one from earlier) emerges and prepares to throw a blast grenade at you. You only have a moment to shoot him before he can accomplish this. If you manage this, move quickly to the panel to the elevators right.

You'll need to enter the code you found back in the personnel files to close the doors and seal off the grenade explosion. Do this as quickly as possible, and you'll close off the elevator just as it detonates.

Backtracking
It is now time to return to an area you may or may not have passed through upon entering the complex. Return Zak back through the conference rooms and back to the previous hallway section. Continue back down the long winding passage until you pass through the security door you opened. Head into the Storage Room to the right of it.

The Storage Room
Head to the far back corner opposite the entrance to the connecting Generator Room. Zak will spot a crate that appears to be concealing something. If you go to the left side of the crate, you can push it to the side and reveal a door.

The Ventilation Shaft
Step into the Ventilation Shafts elevator room. Step on the platform to Zaks left and ride it down to Level 2, heading through the door ahead of you once arriving and into the next milestone.

Possible Deaths

 * Failure to blast the Cartel before he has a chance to throw the grenade or taking too long to close the elevator doors will cause you to be consumed by the blast.
 * Trying to run away from the explosion will prove to be futile.
 * Had you tried heading down to Level 2 before making it to this milestone, the same Cartel would be guarding the next room.
 * Even if you managed to blast him before he could react, a red Cartel sitting in a connecting room would notice this and fill your side with Halon Gas.
 * Trying to break through one of the gates in the shaft would also alert him to your presence.
