Free harvesters trick

[Reactor]

Another tactic from ME using a game bug. It's free, effective, and easy as can be.

NOTE: This tactic is only useful if you're playing against more than one opponent!

If you're playin' wit' Ordos, or you somehow have a Deviator (capturing an Ordos Heavy factory, or obtaining one from a crate), attack one of your opponents, if your army is strong enough. Remember, you'll need a Deviator for this trick, so DON'T lose it in case you have only one. Obliterate the opponent's base, but DO NOT ALLOW the Harvesters to be destroyed. Until the enemy base is finished, simply shoot the derelict harvesters with the Deviator. Once all the hostile Harvesters have been deviated, the opponent's name will disappear from the player list, and the Harvesters will remain yours. I found this trick very useful :)

That is correct, but "other" units won't stay on their butt, and wait, like harvesters

Another good use of this free vehicles-trick (I would call it Dirty Deviator Trick if you don't mind)

If y'wanna have some hostile Combat tanks after you've wiped out your enemy, here'z a good tactic how to do it. It's harder than permamently deviate the Harvesters of course, since Combat tanks can fire without any move, and they won't hesitate to use their given cannons, but if y'can pay attention on them, and you're skillful, y'can do it.

At first, let's go "fishing". Of course, y'need a Deviator. The more Deviators y'have, the more Combat tanks y'can permamently turn on your side. The tactic is the same: If you've totally destroyed your enemy, all remaining deviated units will be permamently deviated,and will fight on your side, nothing can turn it back to normal.

Note that this trick can be done with enemy Deviators, Sonic tanks, Siege tanks,and Devastators too.

So, y'need a Deviator first of course. If y'see enemy Combat tanks approachin', bring them on the front, and try to deviate the Combat tank. If it was successful, pick the Combat tank,and a Deviator in good condition,and take them to a peaceful place, where no enemies,and no worms.

There. They must be next to each other, and the Deviator need to face directly to the Combat tank (or any other vehicle). Even if the vehicle will turn back to normal, the Deviator will re-deviate it quickly.

Note: Be careful though! Don't put these Combat tank-Deviator groups too close to each other, they'll start to shoot the other units around! Never put 2 Combat tanks near the other one!

After you've destroyed the enemy, and his name is disappeared from the player list, you'll have the deviated Combat tanks forever.

Warning! If an enemy Deviator deviates these units, they will never turn back to you! So be careful wit'em!

In case y'have only one Deviator (found in a crate for example), you can do the "Prisoner of war" trick:

Pick the deviated unit, and create a small cage o'walls somewhere near your base (if y'have very less free space, this tactic won't work alright). Make sure there is nothing around,which the Combat tank could shoot at,if it turns back to normal. When you're ready with the cage, drive the tank in, and close it. This tactic is much more hard, and isn't effective, if y'wanna capture Devastators. I think it's really unnecessary to explain,why.

Extreme danger!!! If one of your units surround the cage,when the Combat tank has turned back, the tank will discover that it's trapped,and will start to break out! No matter if you deviate it again, when it turns back, it will start to shoot the walls! So make sure that NOTHING will approach the prisoned unit!

I know, not a very good tactic, but hell, it's funny to fight with Harkonnen and Atreides Combat tanks against the opponent, and it's fun no doubt :) If you like challenges, I insist you to try this :)
