First build 5 Engineers and an APC, Pile the Engineers into the APC, park the APC infront of the opponent's base. Once it cloaks, creep it slowly an inch at a time, keeping it cloaked. Once the APC is deep enough without being seen, unload it and take over 5 buildings. Sell them, you'll get infantry and money.
Defence for Base (ordos only)
In there is a wide ramp buy about 8 cobras and 20 morters and 20 AAtroopers and line them up at the top of the ramp (your base!) with the infantry in between the cobras. Deploy the cobras & morters and they wont be able to get in! If there is a small ramp use 2 cobras, 10 morters and 10 AA troopers! Anything coming in will be Dead* (*but if they send Ikvines or Minotaurs have about 5 laser tanks charge out and keep moving them until the Minotaur/Ikvine is toast)
Harvester Capture
Destroy all of your opponent's Harvesters except for one. Get an advanced carry-all and capture that remaining Harvester and put it in the corner of the map, not landing the Carry-all. Because your opponent still has a harvester left, he won't get another one. Your opponent's cash flow will come to a stop.
How to Use Sonic Tanks Efficiently
First build lots of sonic tanks and move them near the enemys base then instead of sending all of the sonic tanks send one at a time so they don,t kill each other when killing the enemy.
Infantry Defence - Atreides Only
Atreides have to be one of the strongest defenders, with the Machine Gun Tower and the Missle Turret. It is simple to defend with simple Infantry, First find the entrance. If possible find the main one. Build 10 Kindjal Units and 10 Snipers. Place 5 Kindjal and 5 Snipers on either side of the entrance. Deploy the Kindjal and bingo, you've got the kindjal to take out tanks and the snipers to take out infantry.
Infantry Offence - Atreides Only
This works just like the Defence but it can invlove other units. First off, you'll need 10 Kindjal, 10 Snipers and four APCs. Group the Snipers into one group and the Kindjal in another. Load them all into the APCs and find your way to the opponent's base entrance. If there is Infantry Rock near by; the APCs are not needed. First Unload the Kindjal and the Snipers, Line up the Kindjal and deploy them, line the snipers behind them, note this will take place at the end of the rock ramp (ON OPEN SAND) WORMS!!..Okay this is where the APCs come in handy, scatter them around the Map not to far by a fair distance from the infantry..Have them drive around in circles to attract worms, since they are tracked they should to nicely.(Should work 98% of the time..a good waste of money if a worm gets hungry for infantry.) Now any thing coming out of the base should be paste.
Infantry Offence - Counter - Ordos Only
A simple way to take out any offence of infantry, is just a few Mortor infantry, just deploy them at the top of the ramp. Out of ranges of the Kindjal and snipers. They'll get a height advantage and take them out in a few seconds.
Infantry Offence/defence - Ordos Style
The same can be done with ordos, all you need is a mortors instead and The Freman Subhouse. The Freman warriors have same range as snipers and can cloak.
Infernal Offence - Harkonnan Only
For a nice attack force from Harkonnan, not that a few tanks can't take out half an opponents force. First 4-10 Inkvine Tanks and about 25 Flame troopers. With the Inkvines fireing away, and the flamers igniteing the remaining waste from the Inkvine's attacks. Your sure that any Infantry will be ash and you'll be turning tanks into microwaves.
Overwhelming Forces - Ix Sub-House
With any House and the Ix Subhouse, Build a duplicator and one of your strongest units (Ordos:Deviator, Harkonnan:Devisator, Atredies:Sonic Tank ). Build two Adv. Carryalls, and drop them near a base, On rock..I've made that mistake...Deploy the Duplicator, and simply duplicate the unit you brought with it, and just send the units in, not the real one..so you get a free supply of strong units that build in seconds. Another trick to use on the Ordos is to duplicate the enmies laser tanks..The duplicate laser tank will shoot the sheilds will refract and blow both of them up. You didn't pay for your tank so no shead tears. The Laser tank is also great to mass produce..as it is fast and will move away so you can make more.
Sniper Offence
Atreides Only First off, build 6 snipers, If there are barrels around the builds of the base and such..thats all you'll need. If not, add 6 Mongooses and and 8 Bikes to the list. That should do fair, add stronger units as the diff. goes up. This should work when there are two entrances, bring the snipers around rear, and start picking off Infantry{ Or barrels }. All their units should come after the snipers then fly the bikes into the middle of the base to take out defences and the units from behind. Then have the Mongooses paste the base.
