Unties and Area 35 have announced a delay for Tiny Metal, their upcoming military-strategy game inspired by Advance Wars.

The game will forgo its November 21st release date for one a month later, on December 21st. Indie Japanese studio Area 35 noted the reasoning behind the delay is to further polish the game and add some more features prior to release.

Here’s a rundown on the game, via its official website:

TINY METAL is all about the gameplay. We are experienced Japanese video game developers who have come together to develop TINY METAL. We believe that we can bring back the golden age of Japanese videogames, one masterpiece at a time.

We put classical Japanese war gaming into a great modern day graphical package that works well and looks fantastic even on some older systems. TINY METAL features 15 unique units and never before seen gameplay mechanics. TINY METAL is the Japanese Arcade Wargame you wish you had as a kid.

Key Features:

• Flank & Rear Attacks: Flanking and attacking from the rear of an enemy unit confers an attack bonus.
• Radar: Use radars in conjunction with long range artillery to attack enemies outside of your visual range!
• Focus Fire: By using target lock-on with 2 or more units to unleash a deadly focus fire attack.
• Hero Units: Hero units can be called into battle. They are usually outright stronger or more versatile than normal units. Hero units grow stronger over the course of the campaign and can be brought over from mission to mission.

Tiny Metal will launch across PC, PlayStation 4, and the Nintendo Switch.
