Check the mission hints in-game by clicking the flashing light bulb icon near the bottom left of the screen. Also, see the general tips section of this site for hints and strategies that apply to all missions.


A 10-star tourism rating isn't difficult, but it is time- and credit-consuming. A lot depends on how much work you did in the previous Celensoan missions. Continue mining and add a few of the 2- and 3-room hotels now available. More tourists means more income to spend on building. Review the Tourism Tutorial if you need further tips. Otherwise, just keep building, maintaining and cleaning until you get there.

Depending on how long it takes to complete the mission, you may be faced with invasions of Venusian slugs and Fribulan tourists. To prevent the slugs from reaching the base, place a strategic barrier of automatic lasers and high-powered force field posts along each of the two narrow canyons in the northeast corner of the map, where the slugs enter. (This screenshot shows the spot.) The first slug invasion occurs on Day 9, Hour 2, but whether they enter through the upper or lower canyon is random. So it's best to set up defenses in both canyons. If any slugs manage to get close to the base, place more lasers where they're needed. Be sure to buy enough argon to keep the lasers stoked. Try not to let the slugs into the base, as their slime trails make your operatives dirty and lower your hotel's health and hygiene rating.

There's not much you can do about the Fribulan, short of selling all your airlocks so they can't get in. But then your operatives can't get out either. Make sure you have medibays prepped to treat operatives who mix it up with the Frib. (Usually that means Tami and Greg. For some reason, Billy Bob seems to get along great with the aliens.)

Also, keep an eye on Base Conditions in the Bridge Screen and assign someone to repair the objects the Fribulan and human tourists break. A yellow wrench icon above an object means it needs fixing. Place a maintenance post and assign someone with maintenance training to use it. He or she will automatically go to each broken object.

Other tips: If you haven't already been doing so, you may want to move a couple of your operatives from silicon extractors to electronics fabricators. Hoshi and Kita are a good choice here, since they already have the necessary training. The cybernetics lab is not available for making androids, but you can sell electronics for more credits than raw silicon, and you will need 10 units of electronics in the last Celensoan mission, Rebellion.

This just in: Jen has suggested a great strategy for dealing with the monoliths. Near the end of this mission, surround them with forcefield posts. Then, when the next mission begins, the Host aliens will be corralled inside the field. Occasionally one may escape to torment your colonists, but for the most part, they'll remain within the barrier.
