添加了几个适应发展时期的呼叫机械族帮忙的道具，可以在短时间内缓解你的后勤、发展和防御问题。
例如，你可以在刚刚拥有机械师时制作一个呼叫器呼叫一批后勤机械族帮你解决前期的发展问题，或者在遇到进攻难题时呼叫短暂的机械族支援兵。当然，这些被呼叫来的机械族只被允许存活一段时间，它们可以被你指挥因为从一开始它们就会被分配到一个机械师的控制组当中。
Added several items that call mechanical troops to help during the development period, which can temporarily ease your logistics, development, and defense issues.
For example, you can create a caller to summon a group of logistic mech units to help solve early development issues when you first acquire a mechanic, or call for temporary mech support units when facing offensive challenges. Of course, these summoned mech units are only allowed to exist for a limited time, and they can be commanded by you since they are assigned to a mechanic's control group from the very beginning.
