Ogroman (aircraft carrier)

Chapter: C4 · The Aircraft Carrier: Hangars, Bridge and the VTOL
Where: 4-4 Airspace over Aircraft Carrier: Chris flies the VTOL and Piers goes down to the deck

Weak point

Any hit stalls it; Piers's missile finishes it

The finale of a split chapter. First Chris flies the VTOL and destroys the AA guns and 3 helicopters; then Piers runs across the deck to stop a missile (about 4 minutes) while Chris covers him from the air. At the end an Ogroman comes out of the carrier: Chris stalls it and Piers kills it with a missile.

Reward

End of Chris's Chapter 4 (achievement There's Always Hope). Medals Destroyed 3 helicopters with the VTOL's barrel gun and Reached the missile in 3 minutes or less.

Flying Ace (fly the VTOL without a scratch) is Chris-only: watch the VTOL's health in the bottom right and, if it glows red, restart the checkpoint. Don't crash into the helicopters.

Step by step

Phase 1: Chris fires the cannon at the AA guns (green squares on his screen, red squares on Piers's) and rolls to dodge missiles (red icon). Piers runs the missiles: hold the reticle until it fully locks on before firing, or you waste the shot.
Phase 2, Piers: at each container, action button and the timed buttons (1, then 2, then 3). J'avo climb out of a manhole south of him: Chris covers him with infinite ammo.
After blowing the 1st container, Serpent Emblem #16 (Piers's in practice): head towards the stern, slide over the girders and turn right: it's inside a tyre.
2nd container: there are snipers. Chris, shoot the J'avo on the balconies of the building on the left: the AI Chris can't hit them, so in co-op it's your job.
Piers: crawl under a pipe, jump into the trailer, do the launch-console QTE (4 buttons), climb the crane to the end and jump back into the jet.
Ogroman: Chris keeps shooting it (any hit stalls it) while Piers gets back to the jet. Then, when the marker says so, shoot the missile behind it. The missile launching isn't a failure: it's scripted.
