Calling all mercenaries! The eggheads over at R&D have been looking for new ways to expand our horizons, all in order to best demonstrate our firepower on all fronts both physical and digital, and to let the criminal underworld know this: We. Mean. Business. Long story short, we just discovered this new-fangled "YouTube" thing, and by then it had occurred to us that we now have the technology to show off some of our strongest mercenaries we've got to offer! While at the same time, catching instances of goons goofing around on the job, just for that false sense of security if one were to enlist. Which is why we need YOU!

Yes, that's right. It's about damn time to show this world what you're really made of. Whether you're a godly ass-kicker, or a goofy goober, there's always room for a merc like you! If you've got what it takes, then march right on over to [email protected] and hand over YOUR clips, all for the chance at being showcased in one of our future broadcasts. Now GO! MOVE IT!

(In layman's terms: Send us your clips, whether they're cool frags or assortments of funny moments, and we'll put em' in compilations on our official Youtube channel.)

...You're probably thinking, "another downloading tool? this is what, the 4th one?!"

Well it's not without reason. This tool is a stopgap, if you will, between the remnants of our previous two solutions and our next one.

We wanted something that'd help all our current users to update, so with some assistance from our friends over at TF2c, we've been able to put together a temporary solution that should help you update smoothly, regardless of what revision you're currently on. This will also smooth the transition to our new solution which hasn't been completed yet.

Now the reason why that next solution isn't done is due to our commitment to making sure it works perfectly, and due to the scope of the project.

This won't just be for Open Fortress. This'll be for several sourcemods, fixing the downloading solution once and for all. It might be a moonshot but we're aiming for the stars here. Stay tuned for that, but in the mean time, enjoy the new update!

Q: What happened to OFToast II?

A: Unfortunately, OFToast II has been cancelled due to several reasons, mainly stability, efficiency, and the existence of better solutions. Its true replacement however is better, and will be coming soon, hopefully.

Q: What's this new one then?

A: If you're familiar with TF2C's installer then this may look familiar - it's based off of that.

Q: Where's the source code?

A: Here!

Q: Why is it called beans?

A: I'll leave that for you to figure out.

Happy fragging,


Revision 16, Erectin' a Sentry!

OF Team | July 30, 2023

Tags: Updates


Added automatic crash reporting!

  • On first boot, the game will ask you if you agree to sending anonymous reports on crash
  • The only identifiable info sent is your SteamID, more info on

    For some time now we've been concerned about the stability of the game, however internal tests can only help so much, so gathering crash scenarios from the public will be a massive help

Added of_dom_scorelimit_multiplier ConVar

  • Multiplies points need to win in (mercenary) Domination

Added dynamic spawner time settings:

  • of_spawners_dynamic_max_mult - The value weapon spawner respawn times get multiplied by at max player count
  • of_spawners_dynamic_player_start_count - The player count at which
    dynamic weapon spawner times start
  • of_spawners_dynamic_player_max_count - The player count at which
    dynamic weapon spawner times reach their max multiplier

We saw that servers with a larger player cap often ran weaponstay to combat the issue of not enough weapons for that larger player count, however, that deminished the player experience at low to medium player counts, these convars are meant to solve this issue
