Pay what you want for Lockdown Protocol

Do you feel that the price of Lockdown Protocol is not right? Don't worry, now you can get the full version for any price you think it's worth!

When you purchase the full version, this is what you get in comparison to the free demo version:

  • Unlimited access to all built-in and user created levels.
  • One more exclusive player skin for use in multiplayer matches.
  • All future updates for free.
  • Warm fuzzy feeling for supporting a small independent developer.

Go to the Lockdown Protocol page on and you can set the price yourself. The suggested default price is $4.99 USD (roughly 4.5€ EUR) and for practical reasons the minimum payment is set to $1 USD.

Lockdown Protocol 1.3.0 on

The only visible change in this update is a completely redesigned game logo. Besides that, I have dropped my custom full version key mechanism. From now on, there are separate downloads for the demo version and the full version. Both are available on For the first week, the full version is available at -50% discount:

I will send a new key to the people who have already purchased the full version of the game. The custom keys sold before will continue to work with all versions prior to 1.3.0.

Here's full list of changes since 1.2.0 final release:

  • Changed to a completely redesigned game logo.
  • Created a new menu background shader effect that looks better with the new logo.
  • Dropped custom full version keys in favor of separate demo and full version packages.
  • Fixed ugly alpha blending on some UI components.
  • Fixed auto-detection of original XBox controller on Linux.

Lockdown Protocol 1.2.0 released

This update is coming a lot sooner than I expected. There are no major bug fixes, but because I have heard a lot of complaints about annoyingly slow-moving platforms and that has been improved, I decided to put this update out now.

The movement speed of all platforms and elevators has been increased noticeably. Wait times are also a little shorter now. The change might not be as radical as some had hoped, but it's still a big improvement. I even had to adjust completion target times in some platform-heavy levels.

Here's full list of changes since 1.1.0 final release:

  • Increased movement speed and decreased wait times for all platforms and elevators.
  • Increased player walking acceleration to make movement a bit more responsive.
  • Increased player jump height slightly.
  • Fixed randomly missing sentry gun muzzle flashes.
  • Made sentry gun muzzle flash fade in and out smoothly similar to player weapons.
  • Fixed crashes when exiting the game due to an error.
  • Minor adjustments to level completion target times.
  • Removed an unused sound file from installation.

There has been a lot of disturbing news around Desura lately. First, they only seemed to have temporary problems paying the developers, but now it looks like the parent company behind Desura has filed for bankruptcy. It is still possible to purchase Lockdown Protocol on Desura, but due to these circumstances, I strongly recommend purchasing the store-independent full version key here instead.

There are good news too: The full version keys for Lockdown Protocol are now available for purchase at 50% discount for a limited time!

Lockdown Protocol 1.1.0 released

First update to the final version of Lockdown Protocol is here.

The previous version had a combination of compatibility issues that I talked about in the last progress report post here. As I was unable to fix some of the issues with Direct3D renderer I decided to switch to using OpenGL renderer by default on Windows too. Direct3D renderer is still available as a backup for cases where OpenGL does not work.

I have made some changes to score calculation to make the score more dependent on skilled gameplay and less on luck. For example I removed vials in supply packs, because those added a totally random component to final level score. The score given based on level completion time was also slightly increased. Although the scores with older versions are not directly comparable anymore I decided not to reset online high-scores.

This update has actually been ready for some time now, but I was waiting for a code signing certificate. Now that I got it, the game's executables on Windows are finally properly signed, which should get rid of the scary Smart Screen warnings and at least help with false malware detections.

Here's full list of changes since 1.0.0 final release:

  • Replaced all computer generated announcement sounds with human voices.
  • Revert to windowed mode instead of failing if primary monitor can't be detected.
  • Reimplemented decal rendering to fix really slow decal updates with some Windows OpenGL drivers.
  • Show error pop-up on some rare errors previously leading to silent failure.
  • Added '--systemerrors' command line option for enabling more informative Windows error dialogs.
  • Removed unnecessary high-score download for level editor previews.
  • Hid internal unusable trigger elements from level editor.
  • Removed a sentry gun that was too hard to destroy in the 5th single player level.
  • Added a sentry gun to the tutorial level.
  • Removed a couple of obsolete resource files from installation.
  • Supply packs no longer contain vials.
  • Slightly increased the score given based on level completion time.
  • Lowered the total number of spiders spawning from a nest.
  • Added instructions in readme.txt for setting the target time for custom levels.
  • Set OpenGL renderer as default on Windows too.
  • Properly signed Windows executable to get rid of the "unknown publisher" warnings.

Download links have been updated on the game page and the update is available on Desura too.

Progress report

It has been quiet here since the Lockdown Protocol 1.0.0 release. There's no reason to worry, both the game project and I are still very much alive.

I have spent a lot of time trying to resolve some nasty compatibility issues with the game. Unfortunately I have not been very successful in that. It turned out that the Direct3D renderer sometimes simply refuses to work in full-screen mode. The simple workaround is to use OpenGL renderer instead, but that in turn was horribly slow on some machines (specifically AMD APUs). I managed to fix my bad decal implementation which was the root cause for the OpenGL renderer slowdowns, but the full-screen Direct3D problem still persists.

Now that the OpenGL renderer works better, I would like to use that by default on Windows too. Unfortunately it has its own compatibility issues. On some Intel integrated GPUs (at least HD4000) in Windows many of the textures are completely missing and I have not found any workaround to this other than switching back to the Direct3D renderer.

In addition to bug tracking and fixing I have made some minor changes based on the player feedback. For example, I have included a sentry gun in the tutorial level as it's not obvious that you're supposed to deactivate them from behind instead of trying to shoot them (unless you have a really powerful weapon). After four years of playing the game it was obvious to me :D

I'm in the process of getting a proper code signing certificate so I could finally get rid of those scary "unknown publisher" warnings on Windows. This might also help with false malware detections. We'll see how that goes.

One last thing, Lockdown Protocol is being featured in this weeks Freekeyfridays giveaway. This is a chance to get the full version for free!
