None Left Behind

Gabriel Angelos deploys alone to the Planet Acheron against the Inquisitor's wishes to lay a fallen brethren to rest.

NOTE, there is no prep at all for this mission, not even Doctrines.

General Notes

You start with only Gabriel Angelos, having to make your way through light Ork forces and occasionally having to use God Splitter to jump across gaps. There are a small number of health pickups along the way to recover from injuries. Just proceed along the pathways, taking particular note to engage ranged forces as fast as possible.

Eventually you will be joined by a Dawn of War III/Terminator Squad which will add much needed ranged firepower to your forces. Keep moving along the pathways, using Gabriel as a forward tank and the Terminators to unleash heavy ranged firepower.

Eventually you will reveal the Starfort Helios merged with the planet, and will have several positions to investigate. Just keep moving as you have been, eventually you will find Chaplain Diomedes and Eldar forces.

Once you have rescued Diomedes just continue forward, attacking any enemy forces. The Orks and Eldar will also attack each other. Don't be afraid to move one of your Elites back along the map to get to health pickups you left behind, try to avoid having any of them die.

In the final staging area there is an Eldar Fire Prism. The Cyclone Missile Barrage of the Terminators will make quick work of it, but you'll need to be able to see the Prism to do it (and you can warp the Terminators onto the platform with the Prism to help with this). Once the enemy forces are destroyed, you win.
