In the universal war, science and technology are the foundation of everything. Without our engineers and scientists, we even cannot leave the surface of the earth. You must have ever dreamed about being a genius like them. Take a look at the gears equipped on your unit. They can upgrade various kinds of attributes for your unit to increase your potency. But, you know how they are manufactured? We guess not. This weekend, the Alliance will give you a chance to be an engineer!

Obviously, it's impossible for rookie engineers like you to manufacture some complicated devices, such as Engine, Cabin and various kinds of Modules and Chips. Officer Carol has brought an Energy Synthesis to Steel Warship. With this special machine, you can manufacture 3 kinds of Energy Cubes. Of course, you need to collect some materials beforehand. After all, Officer Carol is not a magician.

Core Chip: Buy it from the Ammunition Shop on Steel Warship;
Reserve Battery: Retrieve it from enemies on Blaze Ocean;
Guardian Module: Retrieve it from enemies on Earth Scar;
Assigner: Find Transport Director to swap it with 1000 Rose Quartz;
Energy Lock: Retrieve it from enemies on Blaze Ocean;
Intensifier: Retrieve it from enemies on Earth Scar;
Energy Releaser: Retrieve it from enemies on Mars Wasteland;
Reactor: Retrieve it from enemies on Moon Fortress.

After collecting the materials above, you can combine them into the Energy Cubes with the help of the Energy Synthesis according to the combination rules below:

Energy Cube:
Option 1: Core Chip + Energy Lock (100%);
Option 1: Core Chip + Intensifier (100%);
Option 1: Core Chip + Energy Releaser (100%);
Option 1: Core Chip + Reactor (100%);

Energy Cube II:
Option 1: Reserve Battery (100%);
Option 2: Guardian Module + Assigner + Energy Releaser (high chance);
Option 3: Guardian Module + Energy Releaser + Reactor (high chance);

Energy Cube III:
Option 1: Core Chip + Reserve Battery + Guardian Module + Assigner (low chance);
Option 2: Reserve Battery + Energy Lock + Intensifier + Energy Releaser + Reactor (high chance);

What's the function of these Energy Cubes? Don't worry, Officer Carol will tell you then. They will be the most powerful backup you need in the battle!
