Space Marine 3 could be taken in an absolutely wondrous direction if Saber goes along the idea route of Helldivers 2 and Planetside 2 for one of the gamemodes.

​- Party hub can still be on a battle barge, but to start mission you load up into a drop pod together, while in the drop pod you choose your landing site.
- Small randomly generated maps, or even larger randomly generated maps involving fortresses/hive cities (internal, and out wall areas)

- Primary, secondary, tertiary objectives to complete.

- Randomly generated encounters (eg. saving random squads of guardsmen, stumbling upon and recovering lost relics/equipment)

- 40k galaxy map, different systems could have planets you go to with different biomes.

- Updating, ever-changing war for star systems/planets. Different star systems can be under assault by different enemies (eg. tyranids, tau, eldar, dark eldar, orks, different chapters of csm) that we have to attack and defend those star systems from as a community.

- Larger maps could be played on by larger parties +4 - 9 people smaller maps for smaller parties >4

- Larger maps could have vehicles present, enemy and allied vehicles alike

The possibilities that this could be taken to are endless, you've done so well with Space Marine 2. Keep that momentum going and become a truly legendary studio truly backed by almost an entire fanbase!
