HITMAN 1 Server Optimization

We’ve got some news that we want to share about an upcoming optimization for our HITMAN 1 servers. Our goals here were to give us more flexibility with server scaling and reduce our studios’ daily costs in a low-impact way for our players. We want to stress that this will NOT at any point affect player profile, progression, mastery or any unlocks players have earned.

Starting from April 1st 2020 (14 days from today), players will no longer be able to load HITMAN 1 mid-mission savegames that were created before December 1st 2019. Players that attempt to load an affected mid-mission savegame will receive an error message.

This action will not require a game patch/update, and the process will begin ‘automatically’ on April 1st 2020. The entire process is expected to take between 24-72 hours. HITMAN 2 savegames are not affected in any way. Expanded Information We’ve added some more information in this section to answer some questions that we expect and give more details about this process.

HITMAN 1 mid-mission savegame files currently include lots of data as ‘events’ that we mostly use to evaluate scoring and progression. For example, the events might tell us what items you have picked up or how you eliminated a target.

All of those ‘events’ are sent, processed and stored on our servers. However, we consider them historical data because they are only needed when you want to load a mid-mission savegame that is associated with them. Because they are so closely related, it’s not possible to load the mid-mission savegame and then save it again to try and ‘preserve’ them during this process.

In practical terms, we are paying a daily cost to store these events on our servers, which are only used for loading a mid-mission savegame. In addition, the large (and ever-increasing) volume of events introduces unnecessary scaling issues with our servers, which prevents us from being flexible and agile. Finally, we want to make it clear that we have considered all aspects of this decision and the impact it will have on our players. A key factor in our decision was that the savegames that will become inaccessible do not impact progression in any way and that players who created a mid-mission savegame in the last few months will not be affected. On top of all that, the structure of our game means that you’ll quickly be able to recreate almost every mid-mission save game that was created prior to December 1st 2019. We are confident that the benefit of improved server flexibility and reduced cost will prove to be a significant, long-standing positive for us as a studio. We hope that our players understand, and ultimately accept, our decision as one that is in the greater interest of IOI and our games.

If you’ve got any questions or feedback about this, send it our way on Twitter.

Thanks, IO Interactive



this is probably a good decision. i imagine not many people are still playing on pre-december save games.

i wish HITMAN 3 would be able to run fully offline (except contracts mode, obviously). but i imagine there would have to be a lot of restructuring at IO to get H3 working without any online restrictions. hopefully you guys have considered it :^)


And Ghost/Sniper mode

I would like playing Sniper Assassin offline though


RIP old friend :cry:


That is sad I think, was this too hard to do technically? I could imagine preserving them in this way is still a tiny fraction of the huge pile of data.

I kind of expect there is a different solution for H3’s end of life cycle, like a full offline mode except for the contracts. It is the end of the trilogy after all. There probably is a fanbase which sticks to it as it likely contains all three games.


Go finish all that saved missions :slight_smile:

Tu n’as pas fait souvent de sauvegardes manuelles. :man_shrugging: Les miennes doivent dater de 2018 toutes. :upside_down_face:

There are quite a lot of slots, I usually only use the first 6 and I never wanted to overwrite this march 2016 save because of nostalgia <3

Semi-related, Microsoft’s Azure cloud storage is… uh… full.
H2016 + H2 store their/our data there.
This probably has little effect on us as IO likely has reserved the storage they need and will have less trouble when the H2016 data has been cleared like Clemens announced.



Thanks for still caring about HITMAN™.

The only thing this game needs now is FULL Offline Support:

  • Ratings
  • Unlocks
  • Saves/Progression

Of course you can still make the game able to check online connectivity from time to time and players will play Contracts online. But a full offline support for a singleplayergame like that is essential.

Thanks for caring and considering that.
