Quick answer

There is no officially confirmed "biggest impact round" list yet. The Steam page advertises 30 unlockable ammo types, while community tests report the launch build containing around 21 — the exact count is 待确认 (unconfirmed). What players have verified in practice: two shell families do the heavy lifting (area-effect HE/HCH and precision AP), and community reports describe a special atomic shell with an enormous blast radius. This page separates confirmed facts from community claims.

What the official page says

The Steam page advertises 30 unlockable ammo types for the base game. That is a marketing figure from the store description, not a per-shell data table. The game also lists 20+ abilities and 100+ medals on the same page.

What community tests report

Community guides written from the launch build report a smaller inventory than 30:

  • HE / HCH family — area effect for soft targets; the blast can damage friendlies in range.
  • AP family — precision work on supply depots and fire direction centers, or when friendlies sit close to the target.
  • An older community guide lists 21 shell types in the launch build and warns that any list containing shells named PYRO, TGAS, or PGAS describes the outdated demo build.

The conflict between "30 advertised" and "21 in the build" is real and unresolved — treat any exact shell count as 待确认 (unconfirmed).

The "biggest impact" candidates

Community reports on the highest-impact ammunition:

  • Atomic shell (ATMC) — reported in a community guide as costing 666 credits with a 3 km blast radius. This is a single community source; the numbers are 待确认 (unconfirmed) and not yet cross-verified.
  • HE with maximum charges — a community guide states HE is the only shell allowing 7 maximum powder charges while other shells cap at 6. Also 待确认 (unconfirmed).

No shell has an officially published damage, blast radius, or cost table as of August 12, 2026. Any site that prints exact per-shell numbers is printing community data.

How to choose a round for maximum impact

Until official data exists, the tested rule of thumb is:

  1. Match the target family, not the biggest number — area shells for soft targets, precision shells for supply points.
  2. Mind the one-way rule: dispensed charges cannot be returned, and a rammed shell cannot be pulled out.
  3. More powder charges mean lower elevation and faster flight time (community-tested), which matters for time-sensitive targets.

Why this page has no damage table

Because there is no verifiable official damage table, publishing one here would be inventing data. When the developer publishes per-shell values, this page will be updated with a real table and a source. Until then, treat every "biggest impact round" claim on the internet as community data.

Sources and update note

  • Official Steam page — "30 unlockable ammo types".
  • Community guides (allthings.how, xmodhub) — 21-shell inventory, ATMC details, HE charge cap; labelled as community data and internally conflicting.
  • Community-tested play reports — HE/AP families and the one-way rule.

Exact numbers are unconfirmed; the families are community-tested. Last checked August 12, 2026.
