Ota2xta

The energy buildtree:

The energy tree for xta, differs from ota in several aspects.

The basic energy structures are the same, windmill, and solar collector.

However there are some differences:

The solar collector, DOES NOT COST ENERGY to build, this gives a quick solution to energy stall problems, at a cost of course, 145 metal. Despite the slight high metal cost, solar collectors are heavy armored and do have a constant output of 20 energy units.

Also the enrgy storage (aswell as the metal one) capacitys have been greatly increased, to 32k in energy and around 12k for metal storage.

This makes for a better energy and metal resource management, without the hassle of having to build lots and lots of storage.

For the lvl 1 gameplay this is the main difference.

When going to lvl 2, start the major changes/advantages:

There is a "midway" fusion energy plant.

The mini fusions:

Each side has its own, core ones produce +300 e and are built by lvl 2 builders, while arm ones are built in the level 2 tank lab, and produce silgth more energy (440 e) at sligth more efficient cost.

The Big Fusions have changed aswell.

Now the Cloakable fusion, takes the place of what used to be the normal fusion, that is, it produces 1000 energy and has a small penalty in its cost compared to minifusions, and to big fusions, but it almost completelly stealth once its cloaked and within radar jammer range.

Now be carefull.

The BIG fusion makes 3k energy, and has a very high cost (nenergy metal and BT), altough its somehow more efficient than cloakable fusion, the unit is what used to be the original fusion, so DONT BUILD IT RIGTH AWAY. This big fusion is intended for late game, when you will need huge armies or mass nuclear weapons.
