Okay you know the map 'Suburban Slaughterhouse'(I think that's the name) in any case, it's the one that in kanes challenge you fight the steel talons I think. This one map has something very special, it has this one island in the corner of the map that you drop units on, even surveyors...
Start the skirmish on 'Suburban Slaughterhouse'(if this is the wrong name I'll fix it) preselect the spawn in the left of the map. Make it the maximum amount of resources. Set your faction to Nod* and set the AI to Black hand brutal(or just easy in order to get the hang of this tactic),turtle. Start the game and make these thing in this order;
2.The nod's surveyor. Set the waypoint to as close to the island as you can.(While your MCV is building is a good time to find it.)
Once you have number five have your surveyor call in a transport to drop it off at the tower. Deploy it by the time you get to eight it should be done, put the crane down on the lower bit of the island. Once nine is done put it any where on the island. Don't put any thing on the island enless I say it's Okey Dokey. Put eleven on the island where it'll be out of the way of future buildings. Build twelve and start deploying rocket squads.
If you can before the AI get to you maybe make a temple of nod on the island.
Now I know you thinking that ''Okay that's great but without money it doesn't do you any good."
That's where six and seven come in. Train a couple of saboteurs and send one to every tiberium spike on the map. Make three or more reckoners for every Spike you capture. Train one rocket squad and one black hand for every reckoner(Make sure evey reckoner has one of both.) Send the reckoners to your tiberium spikes and deploy them.
That should be enough to keep them safe.
I intend the island to be more of an insurance so try to keep your main base working and in the fight, but if it's destroyed or no longer helpful you can wage guerrilla warfare from your backup base. It helps to have a couple of verticals to keep you safe from artillery.
*No GDI faction works because their airfields don't fit on the map and the black hand don't have air units. I haven't tested with the skrim yet.
Yesterday I tried out the basic idea and it worked pretty while but my island kept getting hit with vapor bombs so I added the stealth tower.
I'll go try it now and tell you how it went.
