It would be really helpfull if somebody could post the details on all the structures available ingame.

Makes it hard to plan when I don't even know what I need to buy or save up for.

I believe all the structures accomplish the same thing, they just cost different things. So far I don't think people have found the true winning strategy to structure building early on; this because you can jump out at any time (so what you build is really up to you)

Speed

All righty.

Structures are very important, and the key to a good player.
Of course, a level 4 Metal, and Oil are good to have, and what i recommend if you dont have 5000 metal laying around for a Lvl. 5 structure.

Ion cannon, this is a key part in battle situations, you may use it to shoot down enemy Nukes, or severely damage attacking units ( It drops 10 random units health to 1 ).

Nukes, another key aspect. Nukes are usefull in many situations. Have a colony you want to conquer? Well, send a nuke at it all units in their colony will be affected heavily, and some will be vaporized. The same goes for Outposts.

Scanning and Radar jamming capability are also key, Jam radars to prevent your target to see how many ticks away you are from attacking that Op ( Or colony ).

These will be very helpfull structures, and key to success.

and all of them need lots of Energy

i recomend building a stucture of 5 E

first

And I just used all my metal from the world boost to make units...

But why is this in the guide section? It sounds more like a question to me...

Yeah, the question should me moved to questions.

well useing your ion cannon to hit squads isnt realy worth it at all

it can be worth it in smal battles where u just need to delay 10 units to prevent big losses
and this shuld be moved to sugestions
