All right, the main thing you need to know when going into the game is this: It is ALPHA. It is not completed at all. With that out of the way, I'll move onto other points.
The game is laggy, but still playable. Expect disconnections every now and then. Other than that, joining games is easy. Private matches, however, do not seem to exist. It seems anyone can join a game no matter what password you give the server, so expect to not be playing with just your friends all the time.
Now the gameplay itself. Some of it is yet to be implemented (grappling) but it is overall a pretty fun combat. It feels great to dodge an attack and counterattack. However, beam weapons are extremely OP at this time: Expect to be OHKO'd by them.
This will be fixed in the future, however, since this is only Alpha. Some attacks also go beyond their frames (once again, beams). Overall, however, this is a pretty fun fighting game.
Overall, I highly reccomend it. This is just the first of many planned games from Sunstone Games in this series. I'd highly suggest getting involved with both the game and the community; their both user-friendly. It is also possible to get your OWN
monster into the game series (Colossal Kaiju Combat) in the future, but more of that on the community site:http://kaijucombat.com/community/index.php
Now if you dont want to read that massive wall of text:
TL;DR: I reccomend this game if you have a controller and are a fan of fighting games or just monsters in general. It is still in Early Alpha, so glitches are guarnteed; however, this is still a great game.
