Let's keep this semi-regularly updated.
JAD: Extreme Arcade Preview 1The Hub
Welcome to the hub! If you've played War in Heaven Act 3, it's kind of like the dreamscape, only not as creepy. And much less chanting. Its here in the hub that you can get familiar with things. You can't fire weapons, but you can fly all you want around the place. What good is there in flying if you can't shoot anything?
Well for one, selecting certain objects will give you a little popup giving a quick description about things.

Ah, like here! We have Holley's Ezechiel fighter (right next to a berserked version). By hitting spacebar (or button 2) you'll change into the fighter to see how the handling changes. But I feel we need to go deeper. I need stats! What am I really getting into with this fighter?! And what is that scan mode thing in the directives?

Now here we go. We get a nice rotating model of the ship, plus a bunch of stats that allow me to research the different fighters I can play with for JAD:XA. (Also Holley has taken on the large task of rewriting every single tech room description. Thanks.... I think.)

The scan mode is a lua script that takes the information from the in game stats. It's sort of a slimmer version of what FelixJim made awhile ago (but I did build it by hand, it was just easier that way). By pointing this at the berserk version, we can see how the stats upgrade when Holley goes berserk. (These values have been rebalanced a bit since JAD2.21!)

And by pointing it at other ships, we can see why we should NOT be flying them.

Looking over here, we see the mission ships. These four ships are our gateway to the exciting missions: Drone Turkey Shoot, Boss Duel, Space Race and Endless Gauntlet.

To bring us to the mission, all we need to do is select a ship and hit okay. Also note we can see real quick our past high scores for the mission. For Boss Duel, the options are Time Attack and Score Attack. Time attack challenges you to defeat the boss as fast as you can, while Score Attack challenges you to defeat as many boss waves as possible.
In a week or two, I'll show you a preview of the Boss Duel mission!
