Practical usage and interaction notes:
- Place Basic Assembler Modules next to a unit assembler’s construction boundary so the module faces the boundary you want upgraded. The direction the module points determines which boundary is affected.
- Only one module is needed to raise the assembler tier at that boundary; removing the module immediately restores access to the lower-tier unit.
- Use powered modules when you need an extra input for unit payloads or want to route units/payloads through multiple inputs; use unpowered modules when you only need to raise the tier without adding power draw.
- The module interacts with any of the three unit assembler categories (tank, ship, mech), so it can be used to selectively enable higher-tier builds at specific boundaries while keeping other boundaries at their base tier.
- Because unit payloads are the practical payload types for assemblers, plan your payload routing accordingly: Basic Assembler Modules used as secondary inputs should be integrated into your payload network so required units or resources reach the assembler boundary.
- Keep in mind assembler production rules (requirements and rates are determined by the assembler and configured inputs); the module only affects unit tier availability and optional payload input behavior, not base production rates or recipe costs.
