Last Z Research Costs Atlas — Branch Comparison, Badge Totals, and Unlock Paths
This atlas is the branch router for Last Z research costs: compare badge totals and unlock paths here, then open the exact branch page for node-by-node costs before spending badges.
Use this page to compare every major research branch by badge total, unlock path, and priority role. The main route for most players is Hero Training to Cockpit, Military Strategies, Peace Shield, Siege to Seize, then Field Research.
Quick Answer
Best way to use the research atlas: use this page as the branch router, then open the exact cost page for node totals. For most players, the main route is Hero Training to Cockpit, Military Strategies, Peace Shield, Siege to Seize, then Field Research.
- Best early stop · Hero Training to Cockpit
- Best mid-game value · Military Strategies and Peace Shield
- Largest branch · Unit Special Training at 1,488,100 badges
- Late-game follow-up · Field Research and Army Building
Key note: not every expensive branch is a priority branch. Some trees are foundational, while others are late-game badge pressure that only makes sense once the earlier route is already secure.
Recommended Research Route
For most players, the cleanest badge route is to secure the efficient early and mid-game branches first, then decide whether your account should push deeper into late-game trees.
- Hero Training
- Military Strategies
- Peace Shield
- Siege to Seize
- Field Research
Later pressure branches: Alliance Recognition, Army Building, Fully Armed Alliance, and Unit Special Training are not “do this immediately” pages. They are the branches where badge planning starts becoming a major account commitment.

Step 1: Compare total cost before you commit
Use the totals here to see whether a branch is a quick checkpoint or a multi-month badge sink. This prevents expensive branches from looking deceptively close just because the first few nodes are cheap.
Step 2: Open the branch tree page
Every card leads to a full branch page with the exact node tree, grouped costs, and the real checkpoint that matters before you finish the whole branch.
Step 3: Compare branch order with your account goal
If your account still needs efficient mid-game value, open Hero Training, Military Strategies, and Peace Shield first. If your goal is true late-game badge planning, move into Siege to Seize, Field Research, Army Building, Fully Armed Alliance, and UST only when the earlier route is already secure.
