Custom Games

29 April 2026

I suspect I’m like many historical 4X players in that I often want to play on a particular type of map, be that mountainous, islands, a desert etc. etc. On the other hand sometimes I just want to launch into a game.

That being the case I’ve made sure that Annhexation both lets you get into a game quickly with a bunch of presets but also that it has a comprehensive set of controls over the kind of map you play on and who you play against.

I just wanted so talk a bit about custom games here.

The game procedurally generates the map using various noise functions and in the custom game screen you get access to all the various inputs and weights that it uses. I’ve attached some screenshots below. As you change the sliders the map preview changes in realtime which makes setting things up and understanding what the various options do fairly intuitive.

You can also set a specific seed value for the generation - so if their is a map you find particularly interesting you can always get back to it. At some point I’ll probably allow map saving and sharing too.

Once you’ve got a map tweaked to your satisfaction you can play with that exact map or get the game to generate a new, random, map for you based on your parameters.

I’m looking forward to seeing what people create with this during early access - doubtless I’ll end up tweaking and maybe expanding the presets based on this.
