🔥 What’s Included in This Experimental Preview

This build adds:

Engineer

  • Turret pets are back and better then ever! (the little deployable turrets from legacy)

    • Can only be built by Engineers and self destruct when their ammo hits 0.

  • Deposable and meant for a quick "shore" up while backup is on the way.

Radio Man Expansion / Airstrike System

Communications Tower lets you call in airstrikes remotely through your Radio Operator or Command Truck. Operators will gain access to this in the next few days via a new perk.

Relay Nodes are buildable field extenders made only by the Radioman, designed to be placed in forward positions to expand your strike network.

Airstrikes are now directly tied to your airstrike logistics units:

  • Radio Operator is built from the Barracks

  • Command Truck is built from the Motor Pool

These units are your logistics managers for strikes. They can call in airstrikes anywhere you have Influence, which is defined as the AOE coverage from your base network and any extenders you have deployed. Their call in range is more limited while they are moving.

To expand coverage into the field, you can place Relay Nodes as small, hideable forward structures. On top of that, you can build a Radar Tower at your base to enable remote support and airstrikes through your Radio Operators and Command Trucks. The goal is a connected, expanding network that behaves like mobile coverage, pushing your airstrike reach forward as you take ground.
