ZeldereX Online/Walkthrough

Follow the ZX Video Tutorial, even if you want to learn the game without it
It is vital that you do this as completing each part of the tutorial earns you money which basically gives you back the money you spend while building in the tutorial. You get free buildings!

Buy a research center as soon as you can
This building allows you to advance in the game by researching different areas, and being able to buy more advanced technology or buildings. It takes 2 hours to construct, so the faster you start it, the better. Also, in order to get Intelligence level 1 you need a level 2 Research Center so, if you can log on again later, upgrade it again. (Intelligence allows you to buy and manipulate more gameplay elements, such as mining [income] and bombing [efficient building destroyers]). Getting Intelligence level 1 early on will allow you to build the Mining Platform and Ore Storage buildings. These are very effecent income generators, if you can get online often enough to activate them. If you can not get online very offten, focus more on the Trithium Refinery and Trithium Storage buildings.

Troops are overrated
Don't be an army nut! You can turn off the attack protection early but few players do and most of those don’t attack after doing so. It is quite hard to turn a profit off units early in the round. Land units take 50 full 15% attacks, Hovers 34 and Air units take 63 to pay for themselves. Chances are you will lose one of your units before that happens.  I suggest you buy a couple of laser walls, this should be enough defense for the first week. If you are being pestered by someone, don't try to buy up the units to fight back against them unless you already have 1-2 extra bases. Work on colonizing a new base and upping your Trithium Refinery, chances are you will get out of their attack range soon enough.

Bonuses
Don’t save them for later do them right away. You get double the bonus money during the first three days of the month and $66,000 is a lot of money in the beginning. The $33,000 difference between the first and the tenth of the month might cost you 50 ranks. Bonuses are good for some of those expensive purchases, try to use them wisely.

Be a cheapskate
Money can’t be stolen from you only trithium so relax. Don’t feel the need to have your money spent as soon as you get/convert it. It can be kept forever, it's always worthwhile to save up and again, money cannot be stolen.

The Big Researches
Intelligence and Colonization are the two most important researches in the beginning at a cost of $80000 and $55000 respectively. Researching Colonization allows players to build another base and therefore make more income. Players find they make so little money at the start that it's hard to transport enough to a new base in order to start a strong second base early in the game. Researching Intelligence is expensive and costs precious time but allows players to construct a Mining Platform which increases their income. I suggest you upgrade your primary Trithium Refinery/Storage before researching these.
