since i remeber somoene with the Exact idea of making a Game like this couple Years back ^^
dont just stay with Nurgle… There are 4 Chaosgods which you can do get a nice variety of Enemies and Lore from.
You Guys seem to Love “Papa Nurgle that much” (well he aint the oldes God but still every one calls him Daddy"
You can do Chaos Spacemarines alone as;
Khorne Berserkers(World Eater)
Slaanesh Noice Marines (Emp Childrens)
Psyker/ Rubric Marines (Thousand Suns)
and Yes, we get Deathguard for sure
Look how Inquisitor Martyr got Khorne Enemies made. It looked really Dope when Bloodletters come at you, Phasing in and out!
Possibilites are there for sure
So, cant wait to Shredd some filth with Bone’ead with RippaGun. And please we need some nice Low Gothic talk, like Orcs!!
