The first step is to start one. This is really easy, all that you have to do is click play on the Habitarium link and follow the professor’s instructions.
It doesn’t matter which habitat you choose; just pick one. After he’s given you the basics start buying and building immediately.
Since at the beginning you start off with a bunch of resources start stocking up on cornmeal and apple which will take care of your pets’ hunger and tiredness. Also buy a storage unit, house, and at least one nest.
Make sure to attack the pests which will give you more XP to level up. As you get enough resources, make sure to buy three nests: one for each breed of P3s. Always have nesters to put in each nest. For example: Pinchit in one, Mootix in another, and Larnikin in the last one.
Immediately hatch the eggs to help harvest and rebuild. If you ever run out of nesters, the Professor will supply you with another one. To avoid any of your P3s dying, visit every day and hatch eggs and fix hunger and tiredness. When your population is maxed, you can store eggs in case if a P3 dies or your max population increases. You can also discard eggs to earn 200 XP for each egg discarded!
To speed up harvesting put a fence in front of your storage unit; don’t worry, you can still fix it with soldiers and workers if it gets tattered.
Make sure that you have enough of each resource so that if there is an emergency and you run out of spaces in your house, you can buy food to feed your P3s.
For raiding, make sure that your friends OK it first, or they will get extremely mad at you (feel free to raid me if you need some help or just ask for something and I’ll try to get it for you). Also, when raiding, you send away your soldiers and while they are gone, you can hatch eggs to replace the number. Don’t worry, the P3s will come back even if you have max population, it will just be higher. Example: the circle might say 27/25 population!
Most important of all, have fun, though I warn you, this game is rather addicting!
