BATTLE FEVER is made by one person, and it changes almost every day. These are the changes you can see in the demo, straight from the build notes.

Settings menu, two factories and smoother harvesting

1 October 2026, evening

New Settings menu: pick a graphics level from Low to Ultra (or let Auto choose), turn on a frame rate counter and set the UI size. Open it from the title screen or the gear icon in the side panel.
Two factories: a Light Factory (Motor Pool in the Iron War) for buggies, harvesters and trucks, and a Heavy Factory (Tank Arsenal) for tanks and rocket launchers. Each has its own upgrades and its own look.
The Iron War Guard Tower is now called the Lookout Tower.
Enemy bases now stand on concrete, like yours.
Fixed: harvesters no longer get stuck behind narrow gaps in the rocks.
Build menu buttons react to every click, and the menu stays usable on short screens.
On Easy and Normal the enemy waits a little longer before raiding your harvesters.
In the Tutorial the enemy no longer gets FEVER cards.

1 October 2026

The Super Early Access demo is live: the Tutorial (Iron War) and Night Raid (Modern War), free in your browser.
Ages are now Wars. The dieselpunk age is the Iron War, the standard game is the Modern War.
The Iron War got a rounder, chunkier look: domed hangars, Quonset huts and fat fuel spheres. Tanks wear big dome turrets with team bands and roundels, trucks roll on balloon tyres, and more funnels puff black smoke.
Iron War infantry wear wide-brim steel helmets, khaki greatcoats and round goggles, so you can tell them apart from Modern troops at a glance.
Iron War nights glow warm amber: caged bulbs, porthole windows and big sweeping searchlights.
Night lights are soft, round pools now. Night-vision scopes keep their long green cones.
Soldiers who dive for cover, and prone snipers, lie properly on the sand with their weapon pointing forward.
Balance: tank cannons kill an infantry squad in two direct hits instead of three.
Fixed: a group move order no longer gets lost when one of the units dies just before it.
Privacy: feedback no longer stores your country.
"Buy me a coffee" now goes straight to PayPal.

30 September 2026

Five new Iron War FEVER cards: Creeping Barrage (a red smoke round marks the spot, then twelve heavy shells walk in), Carpet Bombing (three bombers in a V; enemy flak can bring one down), Paratroopers (four Rifle Squads and a Bazooka Team drop where you click), Radio Jamming and Smoke Screen. Plus one hidden surprise.
The enemy plays these cards too, and you get a warning when bombers, paratroopers or jamming come your way.
Heavier combat: tanks rock back when they fire, engines cough black smoke, shell casings fly, soldiers dive for cover, and blasts throw dirt and big fireballs.
Voice lines have subtitles and a speech bubble over the unit that speaks. Toggle them with the CC button next to Sound.
Screen shake is gentler and follows your system's reduce-motion setting.

The in-game "What's new" list shows the newest changes when you open the game.
