Epic has launched new free PC games, but they’re only available for a short period.

This week, the Epic Games Store is treating players to two fantastic free PC games. For a limited time, you can snag a popular mech auto-battler and a distinctive deck-building roguelike at no cost.

If you’re into giant robots but prefer to strategize rather than fight directly, check out Mechabellum. In this mech auto-battler, you’ll assemble an army, customize your units, and deploy them in battle. Your job is to observe the action, devise strategies, and position your troops for optimal counterattacks. You can engage in online 1v1 or 2v2 matches, tackle solo or co-op survival modes, or dive into chaotic free-for-all skirmishes. With nearly 10,000 Very Positive player reviews on Steam, Mechabellum has captured the hearts of many strategists.

Astrea: Six-Sided Oracles offers a fresh take on deck-building by using dice instead of cards. Its unique damage system allows you to inflict harm on enemies, heal yourself, or even injure yourself to unleash your most powerful abilities. The dice come in various types: some are reliably safe, others are perfectly balanced, and some are powerfully risky, ensuring that each roguelike run feels unique. With over 350 different dice to collect, Astrea keeps gameplay exciting. It has garnered just over 1,000 Very Positive player reviews on Steam.

If Mechabellum and Astrea pique your interest, simply log in to the Epic Games Store to claim them. These games will be available for free until Thursday, Oct. 1 at 11 a.m. EDT.

Prime Members can also grab 11 additional free games.
