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 an hour and five minutes to do so, so the faster you do it, the better. Also, in order to get intelligence, you need a level 2 RC, 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]). This will let you have an advantage over other players, as you have new techniques, and will not be frustrated when you realize you have to wait 3 hours to upgrade your RC to research certain abilities.

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. Players will never make back the money they spend on buying a bunch of level 1 land factory units, the battle experience players get from attacking with these units increases score hence rank and this will not help you in the beginning. I suggest you buy a couple of laser walls, this should be enough defense for the first week.

Bonuses
Don’t save them for later, do them right away. You get double the money the first three days of the month, and $80000 is a lot of money in the beginning, and the $40000 difference between the first and the tenth of the month might cost you 50 ranks.

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.
