The L1Z1X Mindnet
I call these guys borg supreme. The L1Z1X Mindnet are a great race to get because they have many advantages. They can buy dreadnoughts for only 4 and their dreadnoughts get +1 on all combat to start. Ground units escorted by a dreadnaught get +1 for invasion combat and you start with one extra command counter in your strategy allocation. On top of all that you also get 4 technologies to start with. Make sure you buy a carrier right away because ground forces need to be able to move and starting with 1 is always a deficit. Get your ships out right away and wait for the production card to be played. Then use that extra strategy command counter to get yourself another carrier.
Build dreadnoughts. They will hold the board are cheap to you and have all the above bonuses. Nobody will want to deal with you either in space or when invading. Do not underestimate the power of the dreadnought when in the hands of an L1Z1X. If you have this race and the secret objective that requires anything to do with dreadnoughts you are sitting rather well. Buy all of your dreadnoughts and carriers then amass fighters and take over everything in sight.
The L1Z1X are a powerful race and with 4 starting technologies it will be easy to continue down one of the tech paths and dominate through not only sheer combat power but also high tech devices. Plan on being the one that starts the fight and others will begin to avoid your space.
