All is Lost Forever | Story missions Mad Max Guide

You will start this mission by walking towards the place where Magnum Opus should be parked. After a short cutscene, you must drive towards the old Chumbucket's Hideout.

Weaker opponents will join the fight, quickly eliminate them.

Once you get there, a battle with Stank Gum will start. This enemy is very fast and he will easily avoid most of your hits, countering them with very lethal attacks with his blades. The key to defeating the boss is focusing on counterattacking the attacks that can be blocked (watch out, as in case of unsuccessful block his counterattack will occur quickly after - this one cannot be blocked). After performing a perfect block, you will have an opportunity to deal few stronger hits.

When in fury, keep attacking Stank Gum.

Few other enemies will join the fight. Use them to fill your fury bar, then use that fury against Stank Gum. He won't be able to avoid so strong attacks and it will become possible to perform a powerful combination of attacks. In general, Max's strong attacks can break Stank Gum's defense, so don't waste time on blindly using the fast attacks. Combining the tactic of parrying enemy attacks and performing strong ones, preferably during fury, is the best way to defeat Stank Gum.

Once the battle ends, you must drive to Deep Friah' Stronghold (after a while you can use quick travel to transport near the stronghold). There, a cutscene will occur, after which you can start the last story mission.
