The game will contain many levels that represent many different locations around the world, players will unlock additional content through each challenge. To clear a level, players have to build a strong defence​​​​​​​ with sufficient energy to withstand the alien attacks.

A hastily produced intro video, just to give you an idea how the game play is ↓ 

There are 2 types of resource:

Energy: Can be generated by power generator (solar panel, Wind turbine, hydroelectric generator)

Mineral: Can be collected from aliens, or mineral tree

The electricity consumption is represented by various enemy types:

The blue slime represents the cooling energy consumption

The red slime represents the heating energy consumption

The alien bot represents the water heating

The bat represents the lighting energy consumption

These facilities can collect the energy from natural resources ( sun, river and wind) and convert it into electricity, which can then be used to power other buildings

Solar panel: The basic generator, cheap, energy generated depends heavily on the sun

Wind Turbine: middle-class generator, it gives more energy than the solar panel, however, it’s more expensive, and needs the wind to operate

Hydroelectric plant: the most expensive one, however, it provides a stable energy current and does not depend on the weather. It needs to be built on a river bank

And in the advanced level with other technology

These structures include laser turrets, cannons, etc. In general, these architectures will attack the incoming aliens. Each of them has a different design with a different range, damage, fire rate, etc. All of the defence buildings need energy in order to operate

Laser turret: cheapest option, have a good fire rate. Best for starter can be upgraded

Cannon: Throw energy balls at the aliens (because they deserve it), low firing rate, but cause devastating damage and has area effect

Tower: have long range but low fire rate

The utilities contain the architectures that can have various functions, such as shield generator, carbon tree and repair centre. We plan to add later but for now, its main usage is to

Carbon tree generates carbon over time. The mineral can then be used to build structures

Shield generator: Generate a shield over time that can be used to block damage, adding a good defense layer to important structures

This is where the players can do the upgrade and research in order to unlock new technologies and buildings. The main interaction with other players also happens here.

Players can upgrade their base level here, a new level will unlock new slot for the research center, so more technology card can be applied. They can also unlock new kind of power plants ( ocean wave, thermal, etc) from here

Every technology cards that the players obtained can be used in different research center according to the categories. By collecting technology cards and different materials dropped from the aliens, players can research a new technology.  (It takes approx. 5 real hours, during this time, other players can come and steal the technology card )

Energy research center

Every energy technology cards that the players obtained can be used here if the player has enough materials. Upgrades will mprove the solar panel’s productivity, construction speed or even give it a new feature.

Defense research center

The new technology of defence system can be upgraded here. It will improve the current defense infrastructure by boosting their weapon stats. Also, it’s possible to unlock new weapons with some special cards.

Utility research center

Utility building can be upgraded here with the corresponding utility cards. New abilities and buildings can be unlocked.

The trading center enables players from all around the world to trade the technology cards they have with other players. This increases the user interaction, as well as provide an additional method for players to acquire the technology cards they need.

With the portal, players can travel to other realm and try to either steal their technology cards ( while they are being researched) or help them defend the raid from other players

The technology cards will play a very important role in the player’s strategy. They can apply it to their current structure, customizing the strategy in order to get past the challenging level as well as improving their performance score to gain more rewards.

The card system should be divided by category ( utilities, wind, sun, hydro) and rarity (common, uncommon, rare, epic, legendary). If the player has completed the card researching, the bonus points from the card will be applied to their current infrastructure. The following variables can be improved through researching:

For every building:

Building Cost

Construction time

Hit point

repair rate

For energy generator:

Productivity

Weather adaptation

For defence structure:

Fire rate

Damage

Range

Recharge cost

The technology cards can be obtained using the technology box, which the user can get from clearing a level with maximum rating ( 3 stars). It can also be rewarded from the in-game activity such as demand response event.
