Hell Let Loose: Vietnam Tunnels
Tunnels are an official buildable feature.The product page explicitly says “Build tunnels.” The frozen material does not provide the builder, prerequisites, placement rules, use flow, destruction method or map constraints required for a complete tutorial.
01 / Product scope
What “Build tunnels” safely confirms
The official wording establishes an active building interaction, not merely decorative tunnel scenery. It does not identify which faction or role performs the action, how players enter or use the result, or whether every map and mode supports it.
02 / Official discussion
Tunnels and helicopters are a named balance pair
The official Dev Q&A running order includes “Tunnel vs helicopter balancing” at 14:50. The frozen excerpt does not contain the answer, so it cannot establish a counter relationship, power level, spawn rule or current released-build tuning.
Supports the named topic only, not an inferred conclusion.
03 / Procedure gap
Builder, limits and destruction remain unknown
The frozen evidence does not establish eligible roles, resource costs, build controls, placement distance, tunnel count, team access, spawn behavior, detection, destruction, rebuilding, cooldown or map restrictions. A reproducible task guide requires current released-build evidence for each field.
