Like Dawn of War II, players receive various bonuses and rewards based on their performance in battle. However, there's more of an impact to your players that simply acquiring gear and experience. Thanks to the appearance of the Chaos Marines, your soldiers will find themselves tainted by the corruption on their souls during each mission, which will affect your troops and their abilities. In fact, this adds a new feature to the game represented by a morality bar which indicates how far you've fallen under the chaotic shadow based on your actions. For example, while I jump jetted on top of the base walls, I could have directed my troops to blast through the gate itself, which would have corrupted my forces because they would have left the few remaining defenders open to future attacks from enemies. I was told that each mission that you take on will have variable corruption objectives that you can be presented with, such as not retreating from the enemy or searching the entire map to avoid its effects, and that there would also be different redeeming missions as well.

Why is this important? You'll gain new abilities for succumbing to this corruption, but you'll also lose a number of bonuses to inherent abilities as well. It's a tradeoff for abandoning the commands of the Emperor. What's more, you'll also have to pay attention to how your actions and decisions affect your troops. Not only will the characters under your command respond to the actions you commit with different comments, but some could be corrupted at times if you choose not to bring them into battle or perform an action they don't agree with in battle. Along with these character options comes the addition of Corruption Gear, specific equipment designed for characters embracing chaos, which boosts your corruption rate while providing different abilities and skills as well. It's up to you to decide whether it's worth it to descend into madness to defeat the Chaos Marines, or if you'll take their gear and potentially redeem it by sending it to the Librarium.
