Wave Defense MOD

Mod changes skirmish mode to wave protection mode. Supports multiplayer. The mod is compatible with Warzone2100 version 4.2.0. Older versions of the game are not supported.

You start in the South frontier of the map. You only have a tiny stip of land available, everything else is blocked (but will be revealed as you go). You have 4 minutes to prepare for the first attack. When the timer goes off, the map grows by 10 tiles, and the enemy reinforcements arrive immediately. Once you clean up the map, the timer starts again, but now you will only have 2 minutes to prepare, and so on.

In order to win, you have to survive untill the whole map is revealed.

Good to know

Enemy waves are always technologically ahead of you. Theoretically, you could research as fast as your enemy, but practically your units will always lag behind.
Number of enemies per wave grows quadratically with time, and linearly with number of oil wells on the map.
Enemy does have VTOL.
Structure limits depend on number of oil wells on the map, and increases with each wave.
Structure limits do not depend on number of players.
You can't save/load.

How to launch

Pack catalog multiplay into a zip archive and put them in autoload.
Put the maps 10c-Stone-Jungle-v3w.wz in the catalog maps Read more https://github.com/Warzone2100/warzone2100/blob/master/README.md#configuration
Add one waveAI to the last slot. AI difficulty level will affect the number of enemy units.
Only the host needs to enable the mod.

Tuning and maps

Choosing a map

You can use any map, but 10c-Stone-Jungle-v3w.wz is recommended. Another mode is supported, when the map is expanding to North, for that you can use the map 10c-ntw_trail10pro2.wz which is provided. Replace multiplay/script/rules/settings.json with multiplay/script/rules/settings.json_ntw_trail10pro2. to use it.

When choosing another map:

must not contain any isolated areas, units may be stuck inside them
must not contain large, sharp cliffs
in the center (or in the south, with one-side expansion) must be an area suitable for your own base building. Spawn points don't depend on location of your HQ.

Tuning

All parameters are in multiplay/script/rules/settings.json:

{
	"protectTimeM": 4, # minutes untill first wave
	"totalGameTime": 90, # time in minutes untill enemies reach the rank 16
	"expansion": 10, # tile growth after each wave
	"startHeight": 35, # initial map height when using one-side expansion mode, or the initial radius otherwise 
	"Kpower" : 0.25, # linear wave growth factor, depends on time
	"doublePowerM": 20, # quadratic wave growth factor, depends on time
	"pauseM": 2, # delay in minutes between waves
	"inWavePauseS": 11 # delay between landings within the same wave
	"Kfinal": 2 # final wave size multiplier
	"expansionDirection": "north"/"all" # expansion direction
	"timeHandicapM": 0.5 # slight lag in research for AI
}

Tricks & hints

Enemies don't make any difference between a structure or a droid. You could use cheap structures to distract them, and get some time
Enemy's droid templates do vary with time, but do not depend on your templates. Try to find more effective propulsion/body combinations.
Enemy doesn't have Sensors units, but has artillery and sensor towers.
In about an hour of game, number of enemies will start growing huge. You should try to win before that time mark.
You can delay next landing by leaving some enemy units alive for some time. This doesn't include VTOL, AA guns, and fortifications.
Don't forget to add more structures, as your limits increase.
About a half of enemy units will have fragile propulsion, so use heavy artillery to your advantage.
