If Im not mistaken it uses the same engine as Pike & Shot? I am a huge P&S fan, and this game seems like the next gen by comparison, with a WH40K theme to top it off. I feel a bit spoiled now

Will it have Async MP like P&S?
Here are some thoughts about a few key areas of improvement I would suggest from watching the previews:
1. An epic soundtrack, similar to the one from Chaos Gate. I think that old classic nailed the Space Marine theme.

2. Unit selection voiceovers. For instance, hearing the raspy, synthesized voice of a Terminator announcing his readiness... Mmmmm...
3. Voiced mission briefings / story dialogue
Those things would imo tie the whole experience together nicely.
I wish you all the best with the release of this game!
Cheers
