KF2 Perk Skills v1040: Bilingual EN/Chinese Reference

This page is a reference of the perk skill trees from a Chinese community guide that listed every skill in English with a Chinese translation next to it. It covers Killing Floor 2 as of update v1040 (2016). Each perk has base stats that grow with level, then five skill tiers (levels 5, 10, 15, 20, 25) where you pick one of two skills. The values below were later rebalanced, so check an up to date source such as perk skills and builds for HoE before planning a build.
