Aeon - Isolated. On an Island. Medieval MvM.

"You're on a secret island base that has the potential to deactivate all the robots that Grey Mann has created. However, Grey Mann found it... And you're caught with your pants down because you don't have any firearms to defend yourselves with. Grab your ol' bottle of scrumpy, your bow and arrows, and defend the base!


This map combines both Medieval Mode and MvM, and a lot of map doodads to make for something unique to the MvM scene.

It also features:
  • 1 mission (Medieval Morgue Intermediate)
  • Two paths to the hatch (lava pool vs beach cave)
  • Custom Upgrades
  • Custom icons for Robots
  • Dispensers that players can claim (and upgrade at the shop!) to help their team mates recover.
  • Usable Spells (canteens disabled completely)
  • Capture points players only can cap for special time-limited powerups.
Most of all, have fun!

Version A2


- Unpacked the .pop files for those that wanna take a peek.
- Changed the CP3 crits buff -> stun bots on capture (bots must be near to unlock the CP)
- Replaced Defense Buff CP (which was useless) -> 100% crits buff
- Regen CP unchanged

Mission (Medieval Morgue Intermediate):
- Wave 2: Changed some scouts to Jarate Masters
- Wave 4: Fixed bug where defeating Heal-on-kill Giant completes the wave.
- Wave 4: Changed Heal-on-kill Heavyweight Champ to Armored Heavyweight Champ
- Wave 4: Reduced numbers of xBow Medics and Heavyweight Champs
- Wave 6: Killing the main boss will complete the mission.

To Do:
- When the wave begins, auto-spawn unclaimed dispensers
- Think of something else for CP2 and CP1 power ups.
- Fix bug where CP3 looks like it's unlocked (but really it's locked)

I would like to point a few things about the map that could be fixed:
  • Robots come from only one area, and the pretty wide beach in mostly unused
  • Soundscapes seem to be too loud at times
  • Players can enter robot spawn
  • Some buffs on points seem to powerful
Overall, the mission difficulty must be increased drastically if you want to keep the powerups and other gimmicks on the map
Think how much would the given money affect players, so that the mission would still continue to be challenging in later waves
Adjust tank health to the total track length, melee weapons are not that bad as it might seem.
Try to keep at least two different wavespawns active at a time

I like the aesthetics of the map even if its in the early stage, also the idea of the final boss, it made me laugh the first time i saw it.

At this moment i simply couldnt check the usefulness of some map features since there was no real need to use them

- Reduced bloom on beach. (or not? I don't know how to do this probably)

- CP @ Lava Pool now grants full heal + Uber Heal buffs for 5 seconds (was trigger_hurt healing for 20 seconds)

- Made spells that spawn on round start have chance to roll regular spell or rare spell

Mission (Medieval Morgue Int)
- Made the mission overall harder, haha.
- Most enemies spawn in different places.
- Reduced money by a lot.

Version a5 released!
  • Remade the map from the ground up.
  • Logic improved greatly due to better experience with Hammer.
Brief Overview of Changes:
  • Removed Custom Upgrades.
  • Removed custom mission Medieval Morgue due to incompatibility.
  • Removed tf_logic_medieval in favor of new weapon stripping system.
  • Added Engineer's PDA. He can build medieval buildings.
  • Added Sniper's Jarate.
  • Added Pyro's Thermal Thruster and Gas Passer.
  • Made ocean soundscape quieter.

Map Mechanic: Ocean Depth
  1. In this map, the ocean surface level is observed by the input by the popfile maker.
  2. Use relays to raise or lower the height of the ocean.
  3. Both are saved automatically after a wave ends (triggered by wave_finished_relay).
Relays for Ocean Depth:
relay_oceanlevel_raise - "Trigger" this one to raise the depth.
relay_oceanlevel_lower - "Trigger" this to lower the height.

Map Mechanic: Mining Bay Capture Point
  1. In this map, the ocean water gets trapped inside the mining bay if the ocean rises, and does not lower via popfile. Only capturing the CP or beating the wave will drain the water.
  2. The mining bay's trapped ocean water only raises mid-wave. It drains instantly the was finishes or is lost.
  3. If the water was raised the prior wave and RED lost the wave, the map will not raise the water height in the mining bay.

Engineer's Ye Olde Medieval Buildings
  • Engineer can build in Medieval Mode! This is only map-side.
Traits: Pros/Cons
Pro: Costs 100% less metal to place the building and has no setup time!
Con: Building starts at 1 HP and does not regenerate.
Pro: Has 200 HP!
Con: Does not level up.
Pro: Requires less metal to setup.
Con: Destruction does not produce ammo scraps.

Each building works technically the same. Here are some other details:
- Health is used as ammo. Must be >200 HP before the special function can be used.
- Automatically reloads (regenerates HP) if greater than 200 HP.
- When it's fully reloaded, it subtracts 12 HP and uses the special function.

Sentry is replaced with...
Wheelbarrow Ballista
- "A Huntsman, a wheelbarrow and a pipe bomb walk into an Engineer's workshop..."
Special function: Shoots an arrow bomb that detonates on contact, or detonates by itself mid-flight.
The bomb has an explosive AoE, dealing 100 damage and igniting (with fire) whoever is in blast radius.

Dispenser is replaced with...
Armored Target Dummy
- "An armored target dummy, for distraction and barricading areas. Otherwise, does nothing."
Special Function: Ubers self (Cannot be damaged) for 2.5 seconds.
Other Function: Has a Wrangler shield, which heals 67% damage taken after attack (effectively 33% damage taken).

Teleporters are replaced with...
Grill Brazier
- "Generates a small health pack that heals allies in radius. And light arrows!"
Special Functions: Upgrades heal amount from the health pack from 20% up to 100%. Touching the HP pack heals allies in radius (and overheals a little)
Other Functions:
- Can always light Huntsman arrows
- Being in radius recharges rechargeable items like Bonk, Sandvich, Invis Watch, Targe... faster for 5 seconds.
- Also gives a speed boost and jump boost for 5 seconds.

KNOWN BUGS and unintended things in the map...
  • Nav is broken, robots get stuck in corner and go through the tank door after capturing.
  • Can use Lugermorph.
  • "Teleporter" self-destructs by repairing during pre-wave setup.
  • Capture point permanently locked after BLU captures.
  • Moai disappear at certain angles due to setmodelscale being weird.
  • "Sentry" is TOO LOUD!!
  • Tank disappears upon being shot by a "Sentry projectile"
  • Probably a lot of other things.
I'm actually only releasing this for the sake of preservation. The bugs / unintended things do sort of break the map completely...

Medieval buildings tweaked slightly. Included:

More metal cost per function.
  • They WILL NOT self-destruct anymore during setup when health is adjusted (scrapped completely).
  • [Fixed bug where tank would disappear upon being hit by a Ballista Arrowbomb. (was because of trigger_ignite touching the tank_boss)

  • Dummy: No changes.

mvm_bomb_extra_t - Send a "ForceSpawn" to this to spawn another bomb. Includes Announcer warning players of another bomb.​

aeon_bomb_extra_cp - For CP1 extra bomb mechanic.​

KNOWN buGs...
- MiniSentry turns into a normal sentry upon leveling Building Health upgrade twice.

about these bugs you said, is this version ready for playing?
You can play it, but I would say it's still rough around the edges. In my test on Potato's, I did find a few game breaking bugs.

To name a few bugs...
- One time the tank door didn't open during a wave, even after CP capture.
- Engineer buildings didn't change to the new ones after about 15 seconds into spawning into the map.
- Pyro gets stuck in ref pose by holding the Thermal Thruster out and touching the upgrade station.
- Forward upgrade station doesn't work until beating a wave once.
- Server crashes if human BLU caps CP1 before the round. (obscure but still a bug)
- Bomb isn't reset after beating wave.
- and a bunch of others.

Next version should fix all of these and others not mentioned.

There were also some issues about clarity in the wave bar and the new weapons like Jarate, Thermal Thruster, PDA, Gas Passer... And Scout can use his Pistol for some reason but Engineer can't? Dunno about that one.

  • cp1_ironman_relay - "Trigger" After BLU caps, RED can cap again after 60 seconds. (Resets at wave end)
  • add_noreturn_bomb_relay - "Trigger" Adds an additional bomb with no return timer AFTER CP1 is captured.

Just so you all know, if you do host this server publicly it does lag like crazy because of how many I/O inputs occur. Startacker! reported about 80% CPU usage on the server, however it did not crash because of how laggy it was.

It did still crash, however.

If one player goes Engineer and destructs/rebuilds fast enough, the game can't keep up and the server crashes. I will implement measures to completely mitigate this. (though I thought I did, but it didn't work!) Otherwise, this map should be playable (albeit laggy).


In other news, layout changes will be made, bug fixes will happen, and entity I/O logic will be cut drastically to keep server performance optimal. This is quite exciting! Thank you for playing.

for sake of clarity, what do those tags do?

bot_giant is probably your average stun aversion tag but the others sound like they have some funny business tied to them
