A mecha action-JRPG with ranged and melee mechanics, mech customization, companion customization and lots more? Sign me the heck up. The style of Ironwing Valiant: Record of Astera looks awesome, and we definitely have a lack of really good modern mech games like this.
Ironwing Valiant is a fast-pace, mecha action-JRPG game with shooting and melee mechanics, mech customization, companion customization, real-time with pause command abilities in combat, and a compelling storyline and characters. Taking the guise of a young mecha pilot named Reinhardt, you will battle through sleepy villages, imposing fortress cities, and war-scarred industrial centers, fully customize your Valiant (our term for mecha) to fit your playstyle. The game features full parts customization (Head, Arms, Legs, Core, minor components), a large selection of unique melee, ranged, and axillary weapons, companion and party customization, multiple enemy types (Infantry, armored vehicles, mechs, elite enemies, and more) and a JRPG-style storyline.
Like a colourful Armored Core mixed with Valkyria Chronicles. Do you need any more than that? Check out their most recent demo trailer below:

According to the developer the game world and story is based off of Chinese and Korean mythology and The Romance of The Three Kingdoms novel! So this is definitely one to watch.
There's a very early demo on their itch page and you can follow it on Steam directly too. An upgraded demo is also currently in the works but there's no release date set for the full game yet.
