About this game
Description
Supplied by the Steam store
No one has yet been able to complete this Brutal 10-Day Cycle! Everything is in your hands. - Orilande
Anomaly Protocol is an online co-op survival and horror game for up to 4 players. Mission: Collect valuable relics from dark, ever-changing underground labyrinths, process these items in the surface grinder, and send them to our base in space via rocket.
During the day, you must descend into underground dungeons filled with deadly dangers. While searching for valuable items, you will face not only the darkness but also lurking threats within. Be tactical; watch your back using the mine systems you set up. But watch your step, because you or your teammates can step on the mines you planted just as easily as the monsters can!
- Operate the Base and Complete the Mission If you manage to survive the underground, quickly transport the collected loot to the grinder. Load the processed materials onto the rocket and send them to the base in space. You will earn rewards for every successfully completed shipment. Your rewards will be delivered to you via a special vehicle.
- Go on the Defense When Night Falls Pay attention to the time you spend underground; a warning siren will sound when night falls. When the sirens start wailing, the outside becomes swarming with creatures. Immediately take shelter in your base, connect to the computer terminal inside, and take control of the base's heavy weapon systems. Fight to survive the night and protect the base.
- Upgrade Your Character Strategically use the money you earn for every item sent to the space base:
Skills: Access the "Character" tab from the computer in your base to unlock new skills that will prepare you for the increasingly difficult days ahead.
Cosmetics and Customization: Don't compromise on your style while braving the hardships. Use your earnings to buy brand-new costumes and various distinct headgear for your character.
- No one has yet been able to complete this Brutal 10-Day Cycle! - Orilande For rookie teams embarking on the adventure, the radiation level is kept stable during the first few days. However, do not get complacent; after day 3, the rules of the game get tougher and you will face the real nightmare. For every new day you and your team manage to survive, you will earn a Steam Achievement and prove your endurance.
Gather your team, descend underground, fire the rocket, and protect that base at all costs!
