I have modified a bit this map made by KukY (thanks for allowing me this).
This new map, which is my first map, has been planned for DyDo challenges where you play in position 0 against 2 x DyDo AIs.
There are also scavengers but they are not active in the challenge as I would like to have them allied with DyDo but due to a bug I cannot make the alliance working. Actually if you play with this map in a skirmish game with scavengers active...they will help you as DyDo will try first to destroy the scavengers AI.
I already know someone will be asking "what the hell means dydo3pl001c???" ...dydo="Author" 3pl="3players" 001="my first map" c="challenge".
Strategy:
You have 5 derricks in the base and three oil resources outside of the base.
DyDo has 4 derricks on each base + 2 oil resources outside of each base + 2 oil resources, thought for scavenger AI, also outside of the bases. The 2xAIs have a total of 12+2(scav) derricks and you 8. It should be a medium/hard game because AI has more resources at disposal. For normal player like myself I have not managed to beat DyDo in three games, I assume good players will do but if the AI has too much power I can issue a new version with less derricks for the AI.
There is some small hills around the oil resources outside you base, you can use some them to build fortified positions near your derricks.
I recommend you to play against general 1 on level 5: when the challenge is loaded press "Escape" to stop the game, then type in the console "/set dydo gen1" and then "/set level 5"....
If no issues with the map I will release it with a GPLv3 with the source code too.
