⚠️ This is the official re-release and revival of the original OUTPOST. The first edition was shadowbanned and hidden from search results, but the project is back! This version features completely overhauled zombie spawn rates, progressive wave difficulty balancing, deep performance optimizations (like FPS limits & gore controls), and seamless compatibility for importing your old saves. Welcome back to the wall!

Outpost is a sci-fi tactical defense shooter where you hold the line behind a reinforced barricade against relentless, evolving mutant swarms. As commander of the last bastion, you must deploy automated turret grids, construct critical base subsystems, call in supporting combat troops, and research advanced bio-technology to make the infected fear you.

Outpost Gameplay

  • Technological Progression

    Unlock a massive multi-branch Technology Lab using Mutagen DNA. Research gun systems (Targeting AI, Multishot, Cryo freeze rounds), upgrade automated turrets with the MK-II burst-fire protocol, expand your infantry slots, and spawn clone miners to harvest resources directly from the battlefield.

    Progression

  • Evolving Mutant Swarm

    Your enemies are specialized zombie types with unique behaviors — from swift Runners and explosive kamikaze Exploders to heavily protected Armored units, charging Footballers, and gargantuan Giant bosses that threaten to smash your wall.

    Enemies

  • Base Operations & Waves

    Manage your base infrastructure through a real-time command terminal. Build Hydroponics Labs for passive gold, Fusion Reactors to reduce weapon heat, and Nano-Medical Bays for wall auto-repair. Use your gold to reinforce defenses, buy automated mortars, and survive increasingly challenging waves.

    Endless Waves

GAME CONTROLS

  • Left Mouse Button (LMB): Aim and fire minigun
  • Right Mouse Button (RMB): Fire orbital mortar at cursor
  • Spacebar or Enter : Start next wave
  • R Key: Perform active reload when minigun is overheated 
  • Escape (ESC): Cancel building placement or close popups

Hi! Thanks for reporting the bug.

We managed to reconstruct your original progress from the broken string you provided. Here is your recovered save code:

Very poorly balanced. Normally I would say more, but just none of these numbers and relationships in this game make any sense.

Thanks for the feedback! We haven't deeply focused on fine tuning the balance yet, as our main priority has been building the core mechanics and content.

Fun game, I only managed to get to wave 75, even with all the upgrades maxed out and everything I could buy on max, the monsters always destroy the wall at this point, very fun! Congrats!

Thank you so much! I'm thrilled to hear you had a lot of fun. Reaching wave 75 with everything maxed out is an awesome achievement! Thanks for playing and for the kind words, it really means a lot!!

Thank you so much for playing and for the feedback!

      • Glad to hear you still had fun even without the turrets. Just wanted to let you know that the turret bug has already been fixed in the latest version! Feel free to check it out whenever you get a chance

      When i first started the game, i had the orbital strike already unlocked. It only disappeared after importing a save.

      The building texts sometimes don't reflect the actual upgrade status, for example hydroponics said it produced 80 gold per second, but the upgrade said it only produced 45 gold now and 80 next.

      The fire rate upgrades on the main page seem to do nothing, only those in the tech tree.

      I am unable to build turrets.

      Mortar sprite is misalinged with aim point. Upgrading the mortar also had no effect for me.

      It is unclear to me if the wall reinforcement is a healing or upgrade mechanic. EIther way it did nothing.

      Miners seem a tad overpowered.

      I have no clue what the Elite Guard description means with "Cost: gold %s"

      Thank you so much for this amazing and detailed bug report!

      1. Orbital Strike Access: Fixed. The Orbital Strike button is now hidden by default in the HTML layout, preventing it from appearing before game data is initialized. It remains locked and invisible until you research the "Orbital Strike" technology (costs 1,000 DNA).
      2. Building Upgrade Descriptions: Fixed the index offset issue. Descriptions for the Hydroponics Lab and Nano-Medical Bay now correctly display the status of the current level rather than the next one, aligning perfectly with the stats displayed in the base command sidebar.
      3. Minigun Shop Upgrades: Fixed the formula scaling. Shop upgrades now properly apply their stated values: Minigun Damage now grants +10 dmg/level, and Fire Rate grants +2 shots/s/level (instead of the tiny +0.1 increase).
      4. Unable to Build Turrets: Fixed a critical ReferenceError: cost is not defined bug that was blocking turret placement. Turrets can now be built and placed normally.
      5. Auto Mortar:
        • The Mortar is now truly automatic! It will automatically target and fire at the zombie closest to the wall every few seconds.
        • If you want to fire manually, simply hold Right Click (RMB) to target and fire towards your mouse cursor.
        • The barrel misalignment has been fixed (adjusted anchor offsets), so the cannon sprite now rotates smoothly without detaching from its base.
      6. Wall Reinforcement: Fixed the missing callback hook. Purchasing "Reinforce Wall" from the shop now correctly increases the wall's maximum and current health by +600 HP per level.
      7. Miner Balance: Miners have been scaled down to prevent them from being overpowered. Their base HP has been reduced from 110 to 60, and damage from 55 to 20. They are still great resource gatherers, but no longer clear bosses on their own.
      8. Elite Guard Price text: Fixed the missing string replacement. The description now properly reads Cost: 1500 instead of showing the raw %s placeholder.

      It can be cheesed really easy with the orbital strike,  I think it should be a separated upgrade. After getting the first 3 autoturrets I could skip waves and wait for it to recharge, gain a ton of money to buy more turrets and win easely. The rest is great

      Thanks a lot for your feedback!

          • The Orbital Strike is no longer available by default. It has been moved into the technology tree as a standalone upgrade that unlocks after the Radar and costs 1,000 DNA.
          • No Early Cheesing: The Orbital Strike button is hidden from the HUD, and energy charge accumulation from zombie kills is blocked until you officially research the technology.
          • Tech Progression: The subsequent damage and radius boost ("Orbital Upgrade") has also been integrated into the tech tree as a follow-up node for 2,500 DNA.

          Glad you enjoyed the rest of the game, and thanks again for helping us make it bett
