Sept. 2024

This game is like Gundam Breakers & it's a pretty awesome nice alternative to it. Game is very slept on unless you're mecha savvy, mecha enthusiast, or still want more of the mecha genre itch. I've seen a lot of near 1:1 ratio of players with Gundams, Armored Core, Macross, EVA, Pacific Rim, Transformer or even something unique. The customization on creating your own M.A.S.S or Mecha is insane. This game has a campaign, a 2~8 players PVE, & 1v1 PVP or a 3 on 3 pvp. Definitely a 10/10 game made from a small indie team. It's not made by a bigger budget name studio or corpo either. Just know that it's still in early access. The gameplay is quite clunky still while it's still being polish out. Support these indie devs & let them cook.

I want to point out from the start that this game is about building / customizing mechs. It is like playing with lego just for mechs specifically. Sure, it has a "story" and it does have combat. But that is NOT why you would want to buy this game. The story is ... well its there. The combat is fun and can be challenging enough but nothing to write home about. It mainly serves as a space to use and play around with the mechs you create. So if you like mech customizing then absolutly get this. If all you care about is super fast paced anime style mech combat then this one is okay but I would recommend Project Nimbus. If you want mechs with story go for AC.

June 2024

4 hours spent JUST customizing my mech. Have not even touched the gameplay, yet. 4 hours, well-spent. I regret nothing. UPDATE: 24 hours later I have built 3 mechs. It's taking longer as I continue to master the AMAZING creation system because I'm discovering new tricks to let me bring crazier designs to life. That said..... There is a WICKED learning curve to this thing. There's a 'help' menu that..... vaguely explains things. All of your learning is going to come from hands on experience, a ton of trial and error and just fooling around with everything. But it's WORTH IT. You can customize just about everything about it's looks. You can't really do much with the skeleton besides make it a little bigger. You can't make it smaller than the base size. I presume this is something they've thought about changing. I hope to see. Your appearance and armor have ABSOLUTELY NOTHING to do with your actual stats and performance. So that's a big win there for everyone who likes to keep function and fashion as separate as possible. Pretty much the same deal for your weapons. Fighting style will be determined by the kind of Grip and Attachment. You CAN dual-wield, once you unlock it. You also get missile pods that DO let you fire off a bazillion missiles. Fun, once you figure out how they work, which does not get explained to you..... The Satellite weapons can pack a punch, once you figure out how they work. Yep. No explanation. But there's a pretty nice and GROWING variety of weapon components to experiment with. PLAY WITH THEM. Try them out! They can be pretty cool. My favorites are the Photons and Beam Slasher satellites. The STATS are unlocked in the Development tab. And it is NUTTY how in-depth they've gone with them. You can build and slot your stat boosts pretty much however you want, as long as you unlock the desired nodes. Nodes on the SKILLS TREES! These trees are intimidating at first glance. It's overwhelming to look at and there is almost nothing in the way of tutorials to explain how it works. Just that 'Help' window up in the corner. And..... it could be better. It's an amazing mecha creator wrapped around game play that is kinda..... Meh. It's OKAY? I mean..... It wouldn't be much fun to make the totally awesome giant robots of your dreams if you couldn't take them for a spin, right? Well, that's pretty much what you get here. Build it, take it out, try it out crucible style. Murder waves and waves of trash mobs and get your Main Character groove on..... Then get your butt broken by the bosses. Spoiler: The Blue bar is his shield.... Which needs to be broken before you can damage it. The Yellow bar is kind of like a Defiance bar? Break it and the boss will be stunned for brief period, and then you can start chipping away at the RED bar that is their actual HP. They don't explain this to you either. You're welcome. Good luck. And by the way? Gameplay is how you unlock more parts and components to make cooler robots. But once you unlock them? You can swap things in and out to your hearts content for free. The trick is trudging your way through the gameplay to do it. I think it's worth the effort. There's a TON of potential here. The gameplay is.... only 'okay'. It IS a game. It could be better. It's not completely unplayable but the learning curve is WICKED. But there's POTENTIAL. Devs: MORE TUTORIALS AND INSTRUCTION. These systems are not even a tiny bit intuitive and not really the most user friendly. Fix it. Please. Players.... Play with EVERYTHING. Goof around with sliders and create custom colors with patterns and just HAVE FUN with it. Get stupid. Clown around with it. That's the only way you're really gonna figure out how things work. But it's worth it, once you start getting the hang of it. Don't give up on this game. That goes for the devs too. I hear it's a VERY small team, so they'll need your patience and support. I genuinely believe this CAN get better. It's TOTALLY worth picking up, even if you just spend your time building. Give it a chance and HAVE FUN.

A anime girl yaps in my ear for 10 hours while I use a pillar to punch monsters 10/10

Dec. 2023

This is what I'd call the poor man's Armored Core. Definitely a Gunpla/Mecha fan's wetdream in terms of customization. You could spend hours on just customizing your Mech than playing the actual game. I know I did.
