Featuring Armors, Techs (Ride Armors, Zero- and X-"Modes") and Weapons of the MMX/Z/ZX games
how soon will this be updated for you to use the mech and stuff
Hard to say. If it's two people, probably a good long while, considering they need to update the actual equipment code to the current 1.4 version of release. And it's probably a long while too, considering the differences between individual pieces of equipment, like Z-Saber, ZX-Saber, and Omega-Saber as an example.
And they need to make sure everything is solidly compatible with the base game before working on additional patches for other mods, like ensuring it plays nice with Frackin Universe, as a slight example (Though that can probably be mitigated if the authors work together).
will this work on 1.4.4?
Yes, it does work on version 1.4.4. I also don't think the mod would break even if an update dropped tomorrow, as this mod currently adds nothing that actually affects universe/world files.
You didn't need to do a double post, but anyway...
Assuming you've dropped the mod file into the mods folder in your Starbound directory, all you have to do is open your crafting menu like you normally would and the Construction Capsule should be right there on your list. From there you'll be building anything from this mod using either the Construction Capsule or the Biometal Forge.
How can I equip the weapons like x buster, z saber...
Please read the mod description for the answer. Clearly you haven't, which is why I'm telling you to. This question and your previous one are both answered in the mod description.
