Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“System Arrival combines action RPG exploration and combat with building and defending an underground bunker. Early Access will help us use player feedback to improve the balance, pacing and clarity of these connected systems while we continue developing and polishing the game.”

Approximately how long will this game be in Early Access?

“We expect Early Access to last approximately 4–8 months from its launch. During this period, we plan to improve the game's balance, onboarding, performance and stability based on player feedback. This is a preliminary estimate: the timeline may change depending on the work required. We will share any changes to our plans through Steam announcements.”

How is the full version planned to differ from the Early Access version?

“For the full release, we plan to develop the existing story and progression, refine combat and bunker management and defense, and improve onboarding, balance, performance and stability. Our priorities may change in response to player feedback; these are development intentions rather than guarantees of specific additions or dates.”

What is the current state of the Early Access version?

“Almost all core gameplay systems are already implemented: world exploration, combat with weapons and psychic abilities, character progression, quests, equipment crafting, bunker construction and management, and bunker defense.

All 10 locations are available. The game can be played from beginning to end, with three different endings to discover.

The current version still needs refinement. Players may encounter bugs and other issues, and the balance of individual mechanics, difficulty and progression pacing may change during Early Access. We will continue developing and improving the existing systems based on player feedback.”

Will the game be priced differently during and after Early Access?

“We plan to increase the game's base price by approximately 25–30% when the full version is released. This increase will reflect the refinement of gameplay systems and improvements to the game's quality during Early Access. We will announce the final price and the date of the change in advance through Steam.”

How are you planning on involving the Community in your development process?

“We plan to use Steam Discussions to collect bug reports and feedback on combat, progression, exploration and bunker management and defense. We will publish updates and explain important changes through Steam announcements. Feedback will help us set priorities, although we cannot promise to implement every suggestion.”

About This Game

System Arrival is a single-player top-down survival action RPG with bunker building and management. Venture into a ruined world for supplies, fight with weapons and psychic powers, then return to strengthen your shelter and prepare for the next expedition.

Build your bunker

Build and furnish rooms underground. Turn supplies from your expeditions into equipment and base improvements, unlock technologies and expand what your shelter can do.

Look after your survivors

Assign survivors to gather resources, watch their needs and train their skills. Between expeditions, life goes on in the bunker: its residents need both work and recovery.

Fight with weapons and psychic powers

Aim your shots, strike in melee and dodge incoming attacks. Combine weapons with psychic abilities to protect your character and hit groups of monsters with powerful attacks.

Prepare your defenses

Place barricades and defensive installations, prepare your positions and repel attacks on the bunker. Plan your defenses before the enemy reaches your fortifications.

Choose your moment to strike

Sneak up on enemies and watch for signs that you have been spotted. Reposition in combat and respond to pressure from groups of enemies: the deeper you venture, the harder it becomes to return with your supplies.

Develop your character and study DNA

Combine Intelligence, Constitution, Strength and Agility with skills, equipment and random mutations to find your own playstyle. Study monster DNA to unlock implants, abilities and crafting recipes, and improve armor and bunker technologies.

Find your place in the System's world

A mysterious System has warped reality and turned people into monsters. Among the ruins of modern-day North America, meet survivors, complete quests and choose your responses in conversations. Decide whom to trust: humanity, Earth's AI or the System.
