Part 4

Assault the Orks, kill them all, and speak to the guardsman.

Pick up ammo if needed and go through the bunker door.

Listen to the aggrieved soldiers as you move through the bunker.

Go onto the stairs and keep going until you meet up with Sidonus.

After the cutscene (a non-interactive cinematic the game plays automatically) (an in-game cinematic event), go to the blue support craft and pick up the Chainsword.

To see the Chainsword's execution visuals, perform executions on the Orks that show up.

Leandros mentions in a cutscene that the Orks are guarding the cannon; kill them all.

Continue through a bunker lane, dealing with shooters on the sides of the wall who can use cover (press the cover button to crouch behind walls or objects) (a mechanic where characters hide behind objects to avoid damage).

Move a bit to hit the shooters and take out any Orks on the ground.

When the path branches left and right, go left, destroy barriers by shooting explosive canisters, and pick up ammo.

Go back to the other route to encounter a new enemy that explodes.

From your standing position, shoot the Orks on the wall first.

Encounter the suicide bomber enemy; shoot them from a distance and never let them get close.

Be ready to shoot Grechins and Bomb Squigs that appear.

Shoot the little bomber first to make it explode and take out nearby Orks.

Continue until the game saves and you hear a soldier say "there are too many of them."

Find grenades in the weapons box.

Stay near the weapons box for the first wave of enemies instead of going into the central area, as that is suicide.

Run to the soldiers at the far end for the second wave.

Deal with shooters near explosive barrels; do not shoot the barrels yet.

After the shooters are gone, a wave of Grechins will appear; smash them to bits.

For the third wave, consisting of many Orks, shoot the Ork gunner first, then bombard the Orks when they are in a group.

Conserve grenades for later.

More gunners will appear; shoot them out.

When the Captain mentions the dropship, prepare to use grenades. Pick up more from the two boxes if low on grenades.

Wait for all the Orks to fall out of the dropship and throw all your grenades at them.

If you preserve some grenades, that is great, but use them up if necessary.

After this attack, an Elite Ork will fall out of the ship; this enemy is very tough.

Use combos or grenades on the Elite Ork. If out of grenades, use kicks.

To perform a combo, go near the Elite Ork, hit right click, then immediately hit right click and F. Another combo is RT, RT, RT, F.

Keep kicking the Elite Ork and mash buttons until an execution symbol appears.

Hit 'E' and start left-clicking rapidly to perform an execution. The Elite Ork dies if you hit left-click properly.

After the Elite Ork is defeated, go near the bunker door and go down after it opens.

Speak to the Lieutenant and follow her.

Pick up the purity seal from a yellow weapons craft.

Do not hit the fury button just to see how it works; it will be needed soon.

Follow the Lieutenant outside and continue until you see the Ork Diggah.

Face dozens more Orks. Unleash fury (T) or fall back and shoot from a distance if fury is depleted.

Move to the end of the path and go into the guard post to the left to find an audio log ().

Go back outside and to the right, through a small space between two Diggas.

Pick up grenades from a weapons box in the distance.

Take out two Orks near a Diggah.

Look to the right for more Orks and use grenades on them.

Take out any remaining Orks.

Kill the Orks fighting a soldier, then run to the heavy Bolter, break it, and take it.

Use the heavy Bolter on the dozens of Orks that appear.

Look behind you occasionally to see if any Orks slipped past.

After the Orks are dealt with, go up the stairs at the far end.

At the weapons craft, pick up the Stalker Bolter (the sniper rifle).

Move forward and use the Stalker Bolter on an Ork gunner on the stairs.

Take out all Orks with one shot close to the head using the Stalker Bolter.

Look to your right in the building for more Orks to kill with the Stalker Bolter.

Enter the building to the right of the current one.

Face an Ork on the upper floor of the building.

Continue forward and find a weapons crate.

Opposite the crate is a space to the left.
