S Ranks

There are three factors that determine your rank: Sentinel damage, Terminal damage, and City damage.

Sentinel damage refers to damage taken by your strike team units (Sentinels). To achieve S rank, aim to never get hit, as healing this damage does not improve your score for this factor.

Terminal damage directly corresponds to the lost percentage on the Terminal gauge (visible on the HUD (heads-up display — the on-screen icons showing health, ammo and the minimap)). Similar to Sentinel damage, avoiding damage to the Terminal is the only certain way to get S rank, as restoring Terminal percentage does not consistently improve the score for this factor.

City damage is tracked on the upper right of the HUD and occurs as a result of Kaiju attacks that damage city blocks. Some waves may start with pre-damaged city blocks, meaning City status begins below 100%. Your own attacks do not cause City damage; it is a penalty for leaving Kaiju alive too long.

When pursuing S ranks, prioritize preventing damage to the Terminal first, then to the Sentinels, as the Terminal has the lowest and least-forgiving threshold, followed by Sentinels, and then City damage which has a much higher threshold.

Focus on preventing Sentinel and Terminal damage, as City damage is largely uncontrollable and a consequence of prolonged battles.
