So my gaming group is looking for something fun and different to try while we take a break from our usual games (Pathfinder and Star Wars Saga Edition) and I suggested I would run a 40k game as I love the universe. The group more or less decided to do Only War mainly because they all like the idea of playing guardsmen. However, I imagine Only War lends itself mostly to combat oriented games and while thats fun sometimes, I was also curious about possible roleplay involved.
Anyways, I am wanting to run a one shot adventures for my group (most likely 4 players besides the GM) but I am unsure what kind of adventure to run, as me and my group included have never played any of the 40k RPGs. I was thinking about a mission where the squad has been left behind on a war torn planet and have to fight to survive and escape, I am not sure what enemies are appropriate for low level heroes, but I was thinking traitor guard and I even had the idea of slipping in the option for the heroes to turn traitor themselves for an easy way to escape. Other ideas I had are that the planet is scheduled to be glassed and if they were to go traitor, a warp portal might be their only way off world.
IDK, I am looking for any ideas, as I really want to introduce this setting to my group and have them enjoy it. A one shot is ideal because this will most likely not be a long running game inless the group really enjoys it. But I am more or less looking for recommendations assuming none of us have ever touched one of the 40k core rulebooks, because honestly, we pretty much havn't.
Whats a good one shot adventure idea?
Is there any way the players should build their group to not hinder themselves?
Good ways to balance combat and roleplay.
Are there any rules I should deffinately know about before trying to run a game (besides character creation haha)
Any thing else you think might be useful to a new group and GM.
