A city-builder/FPS.

Defend your colony from the malevolent Geometrics using guns and collect their materials, because God knows you don't have a lot of ammunition left on you. And don't leave the dome, because the planet isn't really habitable; and also don't let the Geometrics destroy your Skydome generator, otherwise it's the same thing as leaving the dome, really. The rather cubic dome.

CONTROLS

WASD, SHIFT, Space: Movement.

1, 2, 3, 4: Change weapons:

• The Colony Manager is not a gun, but allows you to build and upgrade buildings;
• The PDW fabricates its own ammunition, but it's low-powered and inaccurate;
• The Coilgun is accurate and powerful, but consumes ammunition;
• The Shotgun is devastating in CQC, but also consumes ammunition.

E: Interact with highlighted tiles (with the Colony Manager in hand)

R: Reload (consumes entire magazine).

K: Start next night.

What you need to know

You have a fixed amount of ammo mags at the start. You must build Military buildings to generate more on a daily basis. Otherwise you'll be at a disadvantage. Materials, on the other hand, are acquired by killing enemies and by building Industrial buildings.

Keep your power high enough. If you run out of power (and Cubics will drain your generator's power), you lose the game. You can upgrade the generator to increase your power output or its resilience (chance to ignore damage on hit).

You may only build on tiles adjacent to roads (non-diagonally; the grey tiles bordering your generator are roads by default), and may not build on tiles you're standing on. You're also forbidden from building during the night. Unfortunately, you may highlight tiles that you can't build on, so keep an eye out for roads.

Reloading consumes an entire magazine, so spend all of your shots before reloading the gun. Alternatively, stick to the PDW.

More powerful versions of enemies come in later days.

DEFEND THE SKYDOME GENERATOR!

Cubics will try to drain the generator's power...

... and Spherics will try to kill you directly.

Destroy them all during the night!

During the day, you must create roads and buildings...

... and upgrade them later, to keep the colony going.

The main menu screen will tell you the rest.
