Orks will almost straight away attack from the left. try to keep you distance and only engage in close combat as a last resort. try not to run forward without killing the first group or more Orks will arrive so it will cuase more problems.

![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 250](warhammer-40000-space-marine-250-small.webp)
Orks will now come out the pipes next to the steps; use grenades to thin them as much as possable this just makes it easier to kill them all.
![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 251](warhammer-40000-space-marine-251-small.webp)
After you kill most of the Orks this guy will appear, he is a Nob but with really HEAVY armour. use Fury to take him out, it is not impossable to do it without Fury but in this case it is the easist option.
![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 252](warhammer-40000-space-marine-252-small.webp)
If you cannot kill him quickyl and run out of Fury try to stun and execute, it is the best way without loosing to much health, use the normal charge and roll like on all other Nobs.
![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 253](warhammer-40000-space-marine-253-small.webp)
Once you have killed the Orks, take the indicated right tunnel.

![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 257](warhammer-40000-space-marine-257-small.webp)

![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 258](warhammer-40000-space-marine-258-small.webp)
Squigzs will come up behind him, shoot them and they will kill/stagger him.
![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 259](warhammer-40000-space-marine-259-small.webp)
IF it does not kill him, shoot a charged plasma shot at him , this will stagger him again and will allow for close combat advantages.
![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 260](warhammer-40000-space-marine-260-small.webp)

![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 261](warhammer-40000-space-marine-261-small.webp)
When you enter the room you willl see this weapon altar; this altar contains the melta gun. I recomend that you do switch with the vengance launcher. the reason is that the melta is like a shotgun but instead of pellets there is a super heated wave that wipes Orks off the map. it is VERY usefull in a pinch situations even if i does only hold 10 shots.
![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 262](warhammer-40000-space-marine-262-small.webp)
there are some Orks in front of you, use the bolter or plasma gun but do not use the melta even though it is tempting save the ammo.
![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 263](warhammer-40000-space-marine-263-small.webp)
Instead use a grenade or if you wish switch back to the vengance launcher and kill the Orks prgressing with the melta as you switch back again saving ammo.
![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 264](warhammer-40000-space-marine-264-small.webp)
Afte a time you can abandon ranged and just kill with melee. Make sure to stun and execute when health is low.
![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 265](warhammer-40000-space-marine-265-small.webp)
After all the Orks are dead head to the end of the room and grab the ammo box.
![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 266](warhammer-40000-space-marine-266-small.webp)

![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 270](warhammer-40000-space-marine-270-small.webp)

![Warhammer 40,000 Space Marine Walkthrough - Warhammer 40000-Space-Marine 272](warhammer-40000-space-marine-272-small.webp)
