# Wild Hoggs — Last Z: Survival Shooter tools and data > Free calculators, cost tables and a hero database for the mobile game Last Z: Survival Shooter > (also written "Last Z" or "LastZ"). A fan site made by players, founded by Ediva (Server 395). > Every page exists in 15 languages; the English addresses are listed below, the other > languages carry a two-letter prefix (e.g. /de/tools/research/). ## At a glance - 60+ calculators and planners: one per research tree (21), a building calculator with cost tables for 32 buildings, a planner for each of the 36 heroes, plus Mod Vehicle, caravan, exploration (906 stages), hero EXP, hero equipment and the Lucky Discounter - Gift codes, weekly alliance roses, community chat - 15 languages, free, no account needed - Used by 900+ players a day from 330+ game servers (as of 2026-10-06) - Changelog with every update: https://wild-hoggs.com/changelog/ The calculators are interactive and render their numbers in the browser. The pages ending in /costs/ carry the same figures as plain HTML tables — those are the ones worth reading if you cannot execute JavaScript. ## Research trees Badge, power and centrifuge costs per technology, plus research time and prerequisites. Maxing every technology in all 21 trees costs 21,861,224 badges in total. 6 of the trees (New Home, Rapid Growth, Shelter Building, Elite Troops, HQ Management, Army Expansion) cost no badges at all — they are paid for in power and centrifuges instead. The figure after each tree is what that ONE tree costs, not the running total. - [Unit Special Training](https://wild-hoggs.com/tools/research/unit_special_training/costs/): 22 technologies, 1,500,300 badges for this tree -
