This map was initially made as a multiplayer scenario as the name hints but there seems to be an OOS bug each time I play it. Anyways, this map can be fully played through single player with "no" bugs.
All of the information is given in the tabs as well as through chats but I will briefly comment on the scenario as a whole.
The scenario starts with 3 minigame types of objectives. Then there are a series of little objectives until you reach the end.
The first minigame requires you to defend your tower from invaders for a certain amount of waves by attacking with your tower.
The second minigame requires you to force-move enemies to certain areas.
The third minigame requires you to simply move your unit to the finish line, avoiding the obstacles of course.
Then, the series of a dozen or so small objectives will be what you need to complete. Some are puzzles while others utilizes aok intelligence to accomplish the objective faster.
Lastly, cheating is not allowed and not required to win this map. I hope you enjoy it.
EDIT: Forgot to add that there's no walkthrough so if you can't figure it out just post a message here and I'll respond asap.
