Here is an overview of the game, via its Steam page:

About

Kaiju are approaching the city! Scramble the jets and deploy the tanks in this 2D turn-based strategy game.

Command the army!

• We Need More Time! – Play as the mayor of Floatio city, tasked with holding off the overwhelming strength of a kaiju attack. Park tanks and jets in the monster’s path to slow it down (don’t worry, we have a good insurance policy).
• Construct Buildings – Build sacrificial army bases and airfields to distract the kaiju and line the city streets with fodder.
• Deploy Experimental Weapons – Conventional weapons aren’t enough; deploy experimental weapons such as freeze rays and transforming mechas to keep the kaiju at bay.

EVACUATE!

Our chief scientist is working on an anti-monster serum, but it’s not ready yet! Be prepared to evacuate the laboratory using transport trucks, boats or planes when the kaiju get too close.

Fight the KAIJU!

• Five Unique Kaiju – Each specializing in different types of destruction.
• They Mutate – Tremble in fear as each kaiju grows stronger and gains devastating abilities through mid-level mutations.
• Unstoppable! – Kaiju can’t be killed, but can only be slowed down and forced to fall back… for now. Pepper them with ammunition, if you can.
• Predictable! – They move towards the nearest building, and them scientists have mathed the exact odds they step on each tile!

Campaign Mode

• Uncover the Mystery – Strange things are happening: frequent volcanic eruptions, tsunamis and earthquakes. Find out why over the course of an eight-plus hour story-based campaign.
• Embark on a Campaign – Play missions from all over the world as you progress through the globe-trotting fight against kaiju. Test your wits in tactical puzzles, command dozens of units in large-scale scenarios, and fend off repeated attacks while developing your city economically in city defense missions.
• Upgrade your ACES – Veteran ACE units accompany you throughout your campaign. Spend medals to upgrade and customize your top fighters.
• Customize your Project Deck – Unlock powerful Project cards, customize your deck, and bring your best strategy to compete on the online leaderboard!

Play AS the Kaiju!

• Local Versus Mode – Two players duke it out at the same computer (or online via Steam RemotePlay), with one playing as the KAIJU, the other as the HUMANS.

Create Your Own Battles

• Create Your Own City or Scenario – Simple and easy to use, scenarios can be crafted in minutes using the drag and drop map editor.
• Share Your Creations Online – Share your cities or maps online using Steam Workshop integration.
• Compete with Other Players – Gain the top spot on the Weekly Challenge leaderboards.

You thought being mayor of the world’s greatest city was all about zoning bylaws. Then the kaiju came. Good luck.
