Despite the title, this is not related to my other "Salvage the Situation" game.

This is a mix between tower defense and RTS, where you have to defend your base against endless waves of tanks. Where most tower defense games are relaxed, where you set up your defense and wait for waves, in this game you have to micro manage your towers and resource gathering.

In case you skip the instructions, I've copied them here:

Your country have fallen victim to a surprise invasion, and it is your job to pull together a quick defense.
Destroy enemy tanks, and repurpose them for your own needs.

Press the "Build bunker" button to place a bunker build from repurposed parts.
Select a bunker, and click on the enemy you want your turrets to lock onto.
Clicking on wrecks will send out your truck to salvage them for spare parts. Try not to get your truck destroyed, so you don't have to replace it.
With enough tank wrecks collected, you can research auto-targeting bunkers. Click on the big bunker icon to change to and from auto-mode.
Use the number keys to quick swap between bunkers.

The rest of your country is also under attack, so don't expect any reinforcements. You will just have to keep defending as long as you can...
