We've added a page to the Zoids Material Hunters game section that includes some basic gameplay. This is very much a WIP and currently is only covering basic menu info. Half of which we haven't gotten to yet. We hope it can be useful later on.
More importantly though it tells users from the US how to play the game. Normally we don't do this, but for region locked, limited lifetime games (most Zoids mobile games lasted a year or less) we figured it doesn't hurt. English players can even pay and support the game to earn Zoids Gold. We'd like to ask, though, if anyone uses this guide to sign up, to maybe send us any beginner achievements not in the current list? We missed these and can't get them without restarting the game, which would mean losing a lot of progress.
