Zombie Gunship Upgrade Priority: What to Spend Coins On First
Quick n Dirty answer
Max the 25mm before anything else, then add the 40mm, then upgrade reload and bullet speed across the board. The 105mm and the consumables come after the basics actually work.
Zombie Gunship gives you a lot of buttons to spend coins on. Most of them are wasted in the first few hours because the core problem, killing zombies fast enough to not get overrun, is solved by upgrading two guns well, not five guns shallowly.
The 25mm goes first, every time
You fire the 25mm the entire round. Every upgrade to it is felt on every wave, on every map. Push damage radius cautiously here, since a wider 25mm puts more rounds near civilians, but push reload, cooling, and bullet speed hard. A fast, reliable 25mm prevents the wave from ever stacking into a 105mm problem.
Then the 40mm
The 40mm is the middle answer for everything the 25mm cannot solve fast enough, including big zombies. Boosting its reload and damage radius unlocks the safe alternative to the howitzer, especially on civilian-dense maps. Spending here pays off across the whole campaign.
Reload and bullet speed before damage radius
Across all three guns, reload time and bullet speed are the upgrades that change how the game feels. A shorter reload means the next wave does not catch you reloading. A faster bullet means moving threats die where you aimed, not behind it. Damage radius is great on the 105mm and risky on the 25mm; treat it as a per-weapon decision, not a default.
Buy consumables when the map needs them
- Bomb Buddy. One-shot bunker defense if a zombie touches the gate. Worth it on hard maps. Not worth stockpiling, since only one fires per round.
- General Pardon. Extra civilian deaths before game over. Worth it on civilian-dense maps if you are still learning the survivor lanes. Not worth it once your trigger discipline is solid.
- Radar range. Cheap and quietly powerful. Earlier warning is more reaction time.
The 105mm comes last
The 105mm is satisfying, but its upgrades are luxuries. A maxed 25mm and a strong 40mm carry you through most of the campaign on their own. Boost the howitzer once the core is set; before that, coins spent there are coins not spent on guns you actually fire all round.
The one mistake to avoid
Sprinkling small upgrades across every line because they are cheap. Push the 25mm to feel transformed, then move on. Wide-and-shallow loses to deep-and-focused on every map.
