[Have I reached the current limit of the game?]

I'm late to this party obviously. Just got into playing the demo a couple days ago. I'm loving the game, but I'm wondering if I've maybe hit the limit of the demo version at this point in time.

I've started clashing with the corvette medium class ships. But when I show up to explore the crash site, there's nothing there, and the encounter ends after the first turn with no loot.

I also can't seem to unlock any more research items. I have the wolf armor, lazer weaponry, and alenium missles. I've seen some references to vehicle/aircraft based laser weaponry, but no research options.

Have I pretty much seen and done it all at this point?

Thanks in advance!

[What is needed to get lazer weapons?]

Well, there is an item you can make prior to lazer weapons that looks like a lazer pistol, but has no description and does not seem to be useable. He could be referring to that.
