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 a 1-4 player zombie hunting and horror game. The world is split in two: on the surface you are the hunter, underground you are the prey. ABOVE GROUND – The Hunting Grounds Set up in the Safe Zone, fire your Lure Gun and wait for the zombies to come to you. Kill them, collect them, sell them. It's the only way to make money. But a Lure Gun without lures is useless… UNDERGROUND – The Anomaly Zone Lures can only be made from special stones found beneath the surface. Down there, everything is soaked in radiation, filled with rooms no one has ever seen and entities that cannot be killed. You can't fight here; you can only run, hide, and try to carry what you find back up. With every level you go deeper, and both the rewards and the dangers grow.
What you do in the game: - Descend underground and collect lure stones and valuable items - Return to the surface and sell your loot - Draw zombies in with the Lure Gun, hunt them, sell them - Start with no gear or weapons; earn money to buy better equipment, weapons and items - Use the skill tree to make your character more resilient to the dangers below - Spend carefully: your early decisions shape the entire course of the game Warning: There is no difficulty selection. The tutorial is kept as basic as possible. You will discover how this world works on your own. Be ready to die. Many times.

If a teammate is standing a little too still, maybe don't turn your back on them. And whatever you do, don't make it angry.Beyond the Edge The safe zone has a border for a reason. Something old sleeps under the fields outside it, and lately it has been waking up for anyone who wanders too far. If it takes hold of you, pray your team brought enough ammo.Hungry Ground Leave a body outside the safe zone and don't be surprised if it isn't where you left it. Something out there is hungry, and it doesn't like to eat where it finds its food.The Gramophone House There is a house where a gramophone plays. As long as the music plays, you are welcome inside.

-- NEW FEATURES -- 1- A very sneaky entity that constantly watches you has been added to the game! (Update the game to see it). 2- An oxygen system has been introduced to the game! Now, the higher your radiation level, the faster your oxygen will decrease. To replenish your oxygen in the game, you must find oxygen tanks and place them in the oxygen station. Your oxygen can deplete very quickly! So, constantly check the radiation value of the room you are in! Remember: the further you get from the entrance when you go down, the harder it will be to return! 3- The key-earning minigame within the game has been further improved. Note: the minigame is now only 10 rounds, so use your keys carefully! Keys are very important in the game. 4- If you successfully complete the quota after all your friends have died in the game, all your friends will respawn. 5- You will now be able to see the "Sa...
