It's a gundam VS clone for PC. You can blow up mechs and shit.
It has PvE, PvP, CooP, dedicated server program, huge
gay mod community and the ability to use your waifu as a pilot for other people to kill her.
It's a team based mecha
dolphin porn action game, the quickest way to describe it is "Gundam VS clone". Though being a clone it does a lot things differently, like melee weapons handling, having magical girl mechs and moddability.
Chinese mod scene for this game is absurdly large. Supplemented by brazilian, russian and japanese autists the sheer amount of mods for small indie game is absurd. Skins, maps, pilots, music, HUDs, even the full conversions are available. Making brand new mechs was also attempted, but those are mostly remixed movesets/weapons of the existing ones. You still can get more or less functional God Gundam and the like.
Of course you'll need identical versions of game/mods for online play.
You know how modern pink-haired indie "devs" only release local only co-op/pvp games because apparently making netcode for one screen pixel shit too damn hard? Well around 10+ years ago a solitary japanese man not only made fully functional clone of a commercial competitive gundam game, but also made a dedicated server program to go with it, so you can set up games for over the internet or local networks.
Who knows, maybe you can even still find some servers online.
Needless to say server program is bundled with the game, so you don't need to go search for it separately.
Is it in english?
Yes this is english patched 2.008 version, i.e. the last one released before author moved on to the next project.
Pirating is bad/My IPS is on my ass
Well too bad, as you can't buy it directly from the developer for quite some time now as the official site is 404.
There is an "official" english site that sells the original game, i.e. without Power Up Kit update which made it basically 2.0 and doubled the amount of playable mechs. I highly doubt buying from there will benefit creator in any way. And you won't get the latest version.
What's up with the cats
As I said you can mod pilots. But unlike the rest of the game pilots are stored in txt/ogg/png files that you can edit without any special knowledge or difficult tools. Cats serve as a templates for your experiments.
You can find a lot of pilot packs of varied quality made by people floating around.
Will it run on my [toaster/OS]
It should. It's launched through 32 bit exe file, so I assume you can even play it on Linux and Apple OS through emulators and shit.
It werks natively on WinXp and Win7 without any fuckery.
As you can tell by graphics, it's not a demanding game at all, and you still can scale the options in launcher.
Why not just play Gundam VS
Even though I played a lot of Gundam VS games and of course it's objectively superior to Windom, it still has some strong points going for it
Dedicated server program
OC mechs with unique movesets and weapons
A lot of unique intricacies of movement and attacks
I don't remember if GVS series had destructible environment since day 1 or not, but this game has it out of the box. You see that building? You can demolish it.
Say something bad about it
It's old and graphically primitive.
You can remap all keys except movement ones. Have to use glovepie or some shit for it.
All player communities are dead.
Mods are stolen left and right, you can never know who made that alt eisen model - chink, brazilian or ukrainian.
Because of that modding community is dead too.
It's objectively not as good as Gundam VS games, even Vs Zaft 2 Plus on PS2 has 3 times more content and 2 times better graphics if you emulate it.
While game supports arbitrary resolutions UI is drawn for 1024x768 and will always look ugly and stretched no matter what you do and how you mod it.
You can work around it with portraits at least.
Shit like AA and AO has to be forced externally.
