Mission types.
Here a thing, we already have the Comet chase, Astroid missions from CI3. And we have Retro invaders, Droid missions and Supernova missions from CI4. What about CI5. I suggest adding water based missions (i mean we do have a watertight ship), Atmospheric entry missions, Cold planet mission (we do have hot planets, why not. it could even bring about a new equipment) and a crystal cave mission. We could do this by adding planets compatible for the mission such as Water type, Cold type, Hollow type planets. And for the atmospheric entry mission we could put it on any planet with an atmosphere.
