O.C.E (One City Each Sub-Map Pack) 1.1
(+11 NEW Maps)

Welcome to O.C.E (One City Each maps) for Heroes of Might and Magic: Olden Era

This Sub-Map Pack focuses furthermore on gritty, low size, low rez battles, now with the addition of up to 3 heroes (+1 per castle capture in some cases), and up to +3 neutral cities.

(see thumbnail for details).

Installion instructions:

Extract all contents of ‘O.C.E_subpack_1.1 (One City Each maps)’ (.json file and .png file) to your game directory for Heroes of Might & Magic: Olden Era map directory):

Typically:

C:\Program Files (x86)\Steam\steamapps\common\Heroes of Might and Magic Olden Era\HeroesOldenEra_Data\StreamingAssets\map_templates

— If you previously downloaded ‘O.C.E (One City Each Map Pack) 1.0’

‘O.C.E (One City Each Sub-Map Pack) 1.1’ will fit on top of O.C.E (One City Each Map Pack) 1.0.

Just add the contents of 1.1 on top and it will not replace any (keep both 1.0 and 1.1).

— Disclaimer: When using the special upgrade building (as of 12 May 2026 – early access) this will desynch your game.

AVOID AT ALL COSTS!! (*we will implement a fix later down the road) — this is why the disclaimer exists on O.C.E 1.0

Thanks to Khan Games for providing this mod tool.

Yours sincerely,

Boromir (Luca Bravehide)
