Upgrading your soldiers is necessary to take the combat power of your robot army to the next level. There are 2 main different ways to achieve this.
Synthesis (Recruit > Synthesis)
Players can perform soldier synthesis in the soldier synthesis interface in the recruitment section. They can select two soldiers with the same Star Level to synthesize. This will produce a soldier with a higher star rating, and the soldier's attributes will be enhanced massively.
Once the soldiers reach a certain star level after synthesis, new skills will be unlocked.
5, 8, 10 star will unlock Star Skills accordingly.
<aside> ⚠️ When soldiers placed in battle are synthesized, their position in the formation will become empty.

<aside> ⚠️ Soldiers with higher than 3 stars are not allowed to be sold in the trading market.

Soldier Enhancement is divided into two categories: Strengthen (level up) & Tech Research (power-up attributes)
Strengthening will level up your soldier and increase their overall attributes. By using enhancement materials and gold coins, players can upgrade their soldiers' abilities and make them stronger in battle.
