Steam Free Games Guide: Claim These Titles Before 30 December

Steam continues to reward PC gamers with time-limited free game promotions, and December is no exception. As the year draws to a close, players have the chance to permanently add two solid titles to their libraries at no cost. 

With deadlines approaching quickly, knowing what’s available and how to claim these games correctly is essential. This guide breaks down the current Steam free games, explains the claiming process, and highlights why acting before 30 December matters.

What Is Steam’s Free Games Promotion?

Steam’s free games promotions are limited-time offers that allow users to claim selected titles permanently without payment. 

Unlike free-to-play games, these promotions usually apply to premium titles that revert to paid status once the offer expires.

In December, these giveaways are often tied to seasonal sales, publisher celebrations, or promotional campaigns designed to introduce games to a wider audience. 

Once you add a free promotional game to your Steam library, it remains yours forever, even after the deadline passes, provided you claim it in time.

These promotions are extremely popular because they offer genuine value with no strings attached, making them ideal for both casual players and collectors looking to expand their libraries.

Current Free Steam Games You Can Claim

As of now, two games stand out in Steam’s end-of-December free offerings, each catering to different gaming tastes.

Caveman World: Mountains of Unga Boonga is a retro-style side-scrolling platformer that remains free until 30 December at 12:00pm CST. 

Released in 2016 by GrabTheGames, the title features prehistoric environments, traps, enemies, and classic platforming mechanics. 

Despite its low regular price of $1.99, it has earned Mostly Positive reviews from over 400 Steam users, making it a worthwhile addition for fans of old-school gameplay.

The second title, Undercroft Warriors, is a fast-paced twin-stick shooter that extends its free availability slightly longer, until 31 December at 12:00pm CST. With dungeon-style combat and arcade-inspired mechanics, it appeals to players who enjoy action-heavy, skill-based gameplay.

Both games become permanently attached to your Steam account once claimed. However, timing is crucial, as Steam promotions end precisely at the stated times.
