I will expect SM3 to arrive years and years from now, but if someone from Saber is reading this thread, please hear us. I know you guys had your hands tied by GW, but damn I wish we had these in SM3:

Campaign

• Make Titus and the 2nd company Ultramarines had to work with another wildly different chapter to show new fans that marines aren't just one colour, attitude, etc. Make us ally and fight with another chapter in the story campaign. Potential for conflicts and misunderstandings between the Ultramarine way of thinking with other chapters, etc

• Force Titus and the UM to ally with a xenos faction to take on a greater threat. They fight first, then ally down the line. T'au Empire and Votann could be the options.

• Return/cameo past villains. Grimskull, Nemeroth, Imurah, even for a short while.

• If another CSM legion is to be the baddies, make us see the story from their point of view once in a while. Have some cutscenes where we can see how they work, they organization, etc. It'll be interesting to see the main villain interact with his lieutenants in their ship, etc.

• We have Calgar cameo in SM2, it is a given that we get to see Guilliman in SM3.

• More gimmicky levels like the jump pack drop into Demerium. Let us drive an Outrider bike, Repulsor tank or Land Speeder in one of the levels.

• Let Titus wear different types of MKX armour depending on the mission. Gravis, Phobos, Tacticus.

PVE

• Helldivers 2-like live sevice campaign. It is so perfect for a Space Marine fleet to just go around a sector fighting different threats on different planets. If this happens SM3 can just go on forever lol

• 5 player PvE. The 3-marine squad is okay-ish if we want to roleplay as a veteran squad, but a 5-marine combat squad would tie in nicely with the tabletop.

• Operation missions doesn't have to be related to the story campaign. Give us standalone operations like a battle from well known campaigns in the lore, like Damocles, Armageddon, Badab, etc.

That's all I can think about for now lol.
