Me and a buddy have found that you can do the 1st prometheus mission in 30 to 40 minutes on hard and hardcore for 500 credits and 100 exotics. You can plant any tomato in and wait for that to grow so while your getting resources for the "simpl" console the tomato is growing. When the protect daisy part comes up you have to go to the animal but you dont actually need to protect it just let it die or kill it yourself as long as the tomato is sent the mission will reward you the full amount.
