Crash-land on a hostile planet as a CRAFT & Co tool salesman, dig fast, craft laser guns and turrets, and build a fortress that can actually hold, because every night the monsters you have killed come for your base. Real physics means walls collapse, water floods, and only smart building gets you to the rocket that ends it all.

Forts is a physics-based strategy game where you build a fortress in real time, arm it with machine guns, snipers and missiles, and blast your opponent's creation into a smoldering heap. Every wall you add and every shot you take has weight, so a clever design can hold the line or collapse spectacularly. Build, defend, demolish, repeat.

Mindustry mixes factory building with tower defense and real-time strategy. You mine, move and refine resources, feed ammo to turrets, hold your core against waves, then build armies and take enemy bases. It is worth playing for that loop of tinkering, defending and expanding.

Calyx is an RTS and base builder on a hostile Mars-like planet, where the enemy is a spreading alien plant. Mine Ore, keep the power grid alive, wall yourself in, then push back with tanks, flamethrowers and an orbital laser. Every run is a fight to stop the green before it swallows the map.

Warpips is a tug-of-war strategy game where you pick the units and the little soldiers do the fighting. Spawn infantry, tanks and helicopters, call in airstrikes, and push the line to the enemy base. Rounds take 10 to 20 minutes, there is no micromanagement, and every battle plays out differently.
Replayable, Retro
Aliens are after your power cores, and only towers stand in their way.

Easy to start, hard to master, very hard to put down.
