The Epic Games store is kicking off its 2023 giveaway with a big deal, offering a double sale. Kerbal space program and The Shadow Tactics – Aiko’s choice. These new bodies replace last week’s ones Dishonored Definitive Edition and Eximius: Take the front line Copies.

Kerbal space program is a very popular space flight simulation game. Featuring a realistic orbital physics engine, the game lets you manage the space program of the Kerbals, a human race of aliens with little regard for safety.

This is how Squad developers describe the game and its modes:

Kerbal Space Program includes three game modes. In Science mode, conduct experiments in space to unlock new technology and advance Karbelkind’s knowledge. In career mode, oversee every aspect of the space program, including construction, strategy, financing, upgrades, and more. In Sandbox, you are free to build any spacecraft you can think of, with all the parts and technology in the game.

Meanwhile, The Shadow Tactics – Aiko’s choice is an independent extension to Blades of the Shogun, and features the same stealth-oriented real-time tactics gameplay of the well-received original. You will control five assassins, each with unique abilities, to achieve objectives in open maps. A sequel is also in development.

Developer Mimimi Games describes the setup like this:

Although Aiko was sure she had left her old life behind, Aiko’s former sensei, the cunning spymaster Lady Chiyo, reappears from the shadows to challenge her. Together with her deadly friends she sets out to hunt the ghosts of her past…

Both games are given for the first time. When it’s not on sale, the Space Caravel plan is normally $39.99 while Aiko’s Choice comes in at $19.99.

Kerbal space program and Shadow Tactics: Blades of the Shogun – Aiko’s choice Can be claimed for free on the Epic Games Store until January 12, 2023.
