Volatiles combat and waves: the HUD, decoded

Roguelikes live and die on their combat loop, and the Volatiles announcement screenshots are dense with mechanical detail if you know where to look. This page decodes the HUD and combat systems visible in the official screenshots as of October 11, 2026 — observations from the images, clearly separated from confirmed facts.

How do waves work?

Both combat screenshots show the wave system explicitly:

“Wave 5 incoming!” appears centre-screen during play — waves are numbered, escalating, announced.
“Next wave in 13s / Press [N] to start right away” — the between-wave break is a choice. You can wait the full countdown or start the next wave early. Genre convention says hitting early usually trades safety for bonus resources; whatever Volatiles pays for the risk, the option itself is confirmed.

A wave-based structure (rather than continuous spawns) fits the tile-building layer: you place a tile, then face what it brings — the modifers on those tiles (like “hordes appear 100% more often”) directly change how a wave plays out, as covered in the battlefield building breakdown.

What do the weapon slots tell us?

Top-left, three weapon slots sit side by side, each with name, silhouette, and a level tag:

In one screenshot all three read Lv0; in another they read Lv0, Lv1, Lv2.
That is in-run weapon leveling: individual weapons grow during a run, not just your character.
The slots show different weapon silhouettes (a shotgun-like shape in slot 2, a rifle in slot 3 in one shot) — so loadout is multi-weapon, not single-gun.

Between the weapon slots and the health bar sits a pip counter (reading 0/13 and 8/0 in the two screenshots) — most likely stamina or charge charges, spent by the dash/sprint systems the genre uses. Below the weapons there is a second counter reading 0/13 in one shot; take it as a resource meter whose cap grows during the run.

What does the objective marker mean?

Top-right, both combat screenshots show the same line: “7/9 capsules collected” and “8/9 capsules collected”. A collection objective that carries a running count. Two readings:

It is a per-run objective — collect 9 capsules to complete the run or unlock the next stage.
Or it is a persistent narrative counter — the lab wants samples, and each run you bring back what you found.

The story frame (“the lab is watching”, “new knowledge each death”) makes the second reading plausible and thematically tight. Unconfirmed either way; it is one of the first things reviewers will clarify.

How do enemies work?

Enemies are marked with level numbers hovering above them (screenshots show 0, 1, 2 in the opening area and 19, 20, 21 deeper in) — enemy power scales visibly and legibly. That is the genre’s cleanest way to signal “this part of the arena is beyond you right now”. Orange bug-like creatures dominate the shots, of two or three visual variants.

One more combat detail worth noticing: in the machine-interior screenshot, blue energy arcs chain between several enemies simultaneously — a chain-lightning style effect, either a weapon or a placed machine firing. Given that tiles can contain turrets, area-shaping weapons and placed defenses are clearly part of the combat sandbox.

What does the HUD imply about run structure?

Reading the whole screen together — weapon levels climbing mid-run, a resource counter capping at 13 and growing, wave numbers escalating, enemies in the 20s deep in — the run structure looks like a staged climb: survive waves, spend resources, level weapons, push deeper. Combine with the tile system and the death loop (below) and the shape of a run is: plan the arena, fight the plan, die learning, return smarter.

What is still unknown about combat?

Whether hp/stamina regenerate between waves or whether resources are entirely in-run.
Number of weapons — three slots is shown; whether you carry exactly three or hold more is not visible.
Bosses — deeper enemy levels imply elite scaling; a distinct boss layer is not shown yet.
Meta progression effects on combat — “new knowledge” is confirmed narratively; whether it means new weapons, perks, or permanent upgrades is not yet published. See perks and progression for what the UI shows.
