Fast booting 1930s cartoon FPS combat in Iron Curtain Call
Iron Curtain Call’s browser trial loads in 36 MB at /play/, and its full Chapter 1 Steam demo installs cleanly on Windows, macOS and Linux.
The short answer

The nine games at a glance

When a single blockbuster shooter eats 140 gigabytes of SSD space for uncompressed 4K cutscenes, players on laptops, MacBooks and handhelds go looking for small install size FPS games on Steam that download in minutes, boot in two seconds and stay permanently installed without filling the drive. While building Iron Curtain Call as a solo developer in Istanbul, I kept my asset pipeline lean enough that the 60 second browser trial (60 Seconds of War, /play/) streams in just 36 megabytes over the wire, while the Chapter 1 Steam demo installs rapidly on Windows, macOS and Linux.

If you want full retro campaigns that take mere hundreds of megabytes or a couple of gigabytes on disk and load levels instantaneously, start with HROT ($19.99, free demo on Steam), DUSK ($19.99, Windows, macOS and Linux), ULTRAKILL ($29.99, free demo on Steam), Post Void ($2.99) and Ion Fury ($24.99, Windows and Linux). If you want compact high detail horror or anime shooters, play CULTIC ($9.99, free demo on Steam), MULLET MADJACK ($19.99, free demo on Steam) and Quake ($9.99). And if you want a 1930s rubber hose cartoon shooter you can test in 36 MB in your browser or via a free Steam demo today, try my game Iron Curtain Call (out 11 March 2027).

Iron Curtain Call

My game

Play it if you want a 36 MB zero install browser trial or a fast installing Steam demo on Windows, macOS and Linux.

In Iron Curtain Call, stylized 1930s rubber hose ink art means I do not bloat your SSD with gigabytes of photorealistic normal maps. My free browser trial (/play/) transfers in about 36 MB (9.1 MB engine, 27.2 MB pack) and puts you in combat in seconds, while the full Mission 1 Steam demo runs natively on Windows, macOS and Linux.

Why stylized art beats uncompressed bloat

A smaller game means instant restarts and more room on your SSD

When a shooter uses deliberate, stylized art direction instead of brute force 8K textures, it not only saves tens of gigabytes on your drive, it also eliminates shader compilation stutter and thirty second loading bars.

Questions

Questions players ask about small install size FPS games

How small is Iron Curtain Call’s browser trial?

Iron Curtain Call: 60 Seconds of War (/play/) loads in about 36 MB over the wire (9.1 MB engine and 27.2 MB asset pack) with Brotli compression, requiring zero disk installation.

Which lightweight FPS games on this page have a free demo on Steam?

Five games in this guide have a free playable demo on Steam right now: Iron Curtain Call (Windows, macOS and Linux), HROT, ULTRAKILL, CULTIC and MULLET MADJACK.

What PC and indie games are coming out in 2027?

More than one page can hold: Steam shows a lot of PC and indie games with a 2027 date, and dates keep moving. What we checked on Steam on 7 November 2026 are the shooters and the Mac action games, in two dated lists: upcoming FPS games and upcoming Mac games. Iron Curtain Call, our own cartoon noir shooter, is due 11 March 2027 on Windows and macOS, and its free demo is on Steam now.

What games release on 11 March 2027?

Among the shooters we checked on Steam on 7 November 2026: Blood of Rations (11 March 2027) and Iron Curtain Call (My game, 11 March 2027). We only checked shooters, so this is not the full set for that day; Steam’s own Coming Soon page has the rest.

What is a good new single player FPS I can play for free right now?

Iron Curtain Call has a free demo on Steam (Mission 1, about 15 to 20 minutes) and a free 60 second browser trial with no download. It is a single player cartoon noir shooter, and it is our game, so weigh that. For other free shooters, our list of free FPS demos on Steam holds the best rated ones.
