Part 13

Veer left onto an elevated roadway leading onto a bridge.

Stop about 300 meters short of the objective due to a CELL checkpoint ahead with two JAW launchers.

Advance on foot, using vehicles on the right to recharge (use of the HUD (Heads-Up Display) can help track enemy positions).

Use the Predator Bow with an airburst frag to hit milling CELL troops, then use the Bow to kill remaining hostiles.

Enter the building on the left, go down stairwells, armor-up, and jump into the water.

Activate your armor and make your way down ledges.

Concentrate on stopping Archangel.

As you emerge, Psycho will appear.

Hack the Weapons Pod below to upgrade your weapons.

Keep your armor activated as you jump down rock ledges.

A vehicle armed with missiles is near an ammo crate.

Move up the canyon, either by vehicle or on foot; going on foot is easier.

If driving, keep the vehicle intact and pick targets on the cluttered route, staying to the left until you reach a locked gate. Losing the vehicle does not end the mission.

On foot, you will encounter resistance from Ceph and CELL.

When you reach a Pinger, a CELL chopper will approach. Stay cloaked and recharge in battlefield debris or when it's at the far end of a pass.

If the chopper hovers, take it down with a JAW (Javelin missile launcher) by provoking it and then cloaking.

At a CELL position on top of two broken hulks in a shallow waterway, find a crashed chopper for recharge, ammo, and JAWs.

Hack the Automated Turret Gun atop the hulk.

Continue on, staying near the left cliff and recharging between ship halves.

Use your visor to locate the CELL tank ahead and eliminate it with a JAW.

Move past wrecked tanks toward the left side of a stranded ship.

A Secondary Mission for a vehicle upgrade (a tank) becomes available with its waypoint (a marker on your map you've manually placed as a destination) near the left cliff; this is optional and dangerous due to a Pinger and Devastators.

Continue advancing near the cliff, recharging in greenery and behind the tank.

Move from hulk to hulk towards the structure ahead, encountering a Pinger and Devastators.

Sneak past Devastators, scavenge ammo and JAWs, then go up stairwells and open the gate.

Jump the rail and get through the gate; killing the tough Ceph here is optional.

Continue on foot or grab a vehicle.

Go through the circular tunnel until blocked by a wrecked tank. Claire's group is heading to the Archangel Command Center, and the orbital platform has a 15-minute window to target New York City.

Take the Gauss Sabot sniper rifle near ammo crates.

Psycho calls with a Secondary Mission: destroy the generator inside the CELL Command Center powering its air defenses.

Survey the battlefield below the cliffs; CELL troops are battling Ceph.

Locate the zipline on the far left side of the ledge. Cloak and ride down.

Start around the rear of the huge structure.

Jump onto elevated conduits and locate the Devastator ahead with your visor.

Use the Gauss sniper rifle to take down the Devastator.

Equip electric arrows and advance under cloak or use gauss rounds to knock out three Scorchers.

If you kill at least one Scorcher with an electric arrow, grab an Incinerator.

Hack the gate.

Use the Incinerator or Bow to kill the two CELL sentries inside.

As CELL troops migrate towards the gate, shoot arrows through the cloak and retreat to the ramp to recharge.

When opposition wanes, go right, moving up two stairwells.
