Research Priority

All research can be completed over time, but it is still better to set early priorities first.

Top Priority

Infected Elimination

This research improves efficiency for rewards earned from defeating regular infected and infected bosses. It is worth prioritizing early because the gain in daily farming and speed-up items is noticeable.

Top Priority

Alliance Duel

This is a core research line directly tied to Alliance Duel scoring. The more consistently you invest in it, the better your alliance activity efficiency becomes.

Upgrade Sheet Notice
