Fight or Flight

About this game

A Large-scale multiplayer monster hunting shooter game. Featuring multiple game modes including Battle Royale modes.
Also including full offline support with bot ai for practice!

With each passing day the situation grows more and more dangerous as the virus continues to spread, infecting and killing everything in its path.
You are a specially trained operative that will drop into the infected region via an air-drop and attempt to recover artifacts from the infected and eradicate any that remain in the region.

The world is now sprawling with infected monsters and zombies. Be careful out there!




Multiple Game Modes
Each player is pitted against Zombies, Monsters and each other. When a player kills zombie's they collect the elusive "V", which can then be used to track down monsters.

The game features multiple game modes with different objectives. In each mode the player will gain experience in the form of an in-game currency. This can be obtained from completing objectives, killing and harvesting monsters, killing zombies, and killing other players. Currency can then be used to purchase in game cosmetics.

Battle Royale:
Standard Battle Royale mode featuring a moving and shrinking "safe zone"
Players can select a parachute location at the start of the match.
Each player starts with only a Melee weapon.
The players sole objective is to be the last man standing!
This mode is permeant death.

Battle Royale Training:
Battle Royale Training is the same as the Battle Royale mode, but the player gets to choose a weapon loadout at the start of each spawn and starts with 3 lives.

Extraction:
Extraction does not feature a safe zone like the previous modes, the goal is simply to obtain an Artifact by harvesting a monster, and then reach an extraction point within the time limit.
Players can only extract if they have an Artifact on them at the time of extraction.
Players are rewarded for extracting, and extra points based on how many Artifacts they have.
Extraction points are activated 10 minutes after the match has started.
Each player starts with only a Melee weapon.
This mode is permeant death.

Extraction Training:
Extraction training is the same as the Extraction mode, but the player gets to choose a weapon loadout at the start of each spawn and starts with 3 lives.

*All modes can be played with or without AI. All modes also support offline play or host your own servers on a LAN.




Weapons and Attachments!
Fight or Flight was built with realistic weapon ballistic simulation for a tight shooter experience.

Your player can carry 1 weapon of each class (eg, Pistol, Assault, Sniper), for a total of 3 weapons, and 1 melee weapon, which every player will start with.

Each weapon has unique damage, recoil, and bullet flight characteristics, including a penetration and ricochet system.

Each weapon can have a barrel attachment, such as a compensator or suppressor and a sight or scope attachment depending on the weapon. (weapon attachments will be expanded on through the course of development, with plans for more barrel attachments and magazine attachments)

Cosmetics; Simple Tier, Pattern Tier and Gold Tier!



Built on amazing tech!
Fight or Flight is built on the latest version of Unreal Engine. Utilizing modern technologies and crafted with relentless passion for multiplayer shooters. Designed for the ultimate realistic fps experience, with realistic ballistics simulation, modern sound using binaural audio, and breathtaking graphics with features such as volumetric fog and a day cycle that changes as the match progresses.

  Fight or Flight - 0.72 - QOL & Bug fix

  Fixed bug when recording of match tries to be played when it does not exist. Fixed bad AI spawn location at Mill Base. Improved AI avoidance. Tweaked AI skill adjustment. Tweaked "breathing" and "weapon lag" Improved HUD notifications when player tries to extract without an artifact. Fixed late join replication bug with Extraction mode for multiplayer. Fixed issues with LAN dedicated server and client, if you wish to try this there is batch files in the installation folder, read the help file, and close steam before trying this. Its also a small way to get a bit better performance with more bots.!NOTE FOR NEW PLAYERS!:The more bots you have the more strain on your CPU. I personally only play with 8, but others with faster CPU's have reported much more. Just keep this in mind if you are having performance issues.

  Fight or Flight — End of Development

  After much consideration, I've made the decision to officially close development on Fight or Flight. Life took me in a new direction over a year ago, and I simply haven't had the time or energy to give this project the attention it deserves. I'm genuinely grateful to everyone who played, gave feedback, and supported the game during Early Access. It meant a lot. Thank you for being part of the journey. — Jonathan / Outer Planet Studios

  Fight or Flight - 0.71 - TEAM MODES!

  {STEAM_CLAN_IMAGE}/34023766/0b7979f499ab4cd5a4174ffb1ac539d6867b0b19.png This patch brings something different with new Team modes, available in BR and DM modes. Just two teams. Last team standing wins for BR modes, and team with the highest score wins in TDM mode. I have also included a new test/deathmatch level "Test-Industrial" which is a great start to test out Team Deathmatch. In this patch there is also some very important fixes to the AI pathing which will make the matches much better in the BR modes!

  Fight or Flight - 0.62

  Another small hot fix here, posted urgently as i discovered a bug caused by the auto-equip on network clients. Next patch should finally have the factory area replacement done (fingers crossed) along with a smaller deathmatch level based off it, and if all goes well i will implement a TDM mode as requested, and then eventually feed the work done from that into team modes for the other game modes! Thanks for the recent suggestions in both reviews and the forums, its very appreciated. AI; Bots will now only use their pistols for the first 3 minutes AI; Bots will not attack other bots for the first 1 minute AI; Corrected damage on some of the AI weapons AI; Further improvements to bot pathing Player; Fixed new bug with Scopes on network clients Game Mode; Fixed bugs with Deathmatch mode Misc; Fixed bug with radiation hazard sounds effects
