Ah, the weapon slot. I grokked that at the start, but it always seems weird when I go out with the Dom suit on, thinking it's the Maverick, and when I press D Up, nothing happens...
Much appreciated. Right on, Commander!Tip-offs never happen if you apex there directly from taking the mission. The die-roll for those sorts of mission wrinkles ("target fleeing" for assassination/takedown missions being another example) happens when you undock from the station/settlement in your ship.
If they do get tipped off though, don't worry. The mission doesn't update/activate until you're within 2.5km of the settlement. If you touch down outside that radius, before the mission update pops up on the screen and gives you your objectives, the settlement won't turn hostile. You can then disembark and dismiss your ship without it being fired upon.
The Maverick has the cutter, the Artemis has the sampler, but the Dominator really needs something that chimes with its basic military function
