Using the camo before the start like the haste boost is fine for me

True for the teleport

I looked at the rules, they state “Timer starts on first player movement in mission (selecting weapon / throwing object does not count but any player directional input or aiming input does count)” So I figured it would be ok for the haste boost. Also it doesn’t change much if you throw it and start to run or if you start to run and throw it afterwards. I also agree on the clearing of rooms part, I would say that any killing / inflicting of damage to an enemy counts as a time start and any movement be it player or drone counts as a time start if that sounds good.

Really nice, that can be helpful in a lot of place, the invincibility too ( maybe with the pirate betrayal mission, I don’t remember other spot but there are others for sure )
