“Pixel Starships” from about 2016 is a slug-a-thon between fully customizable space ships. You’ll mostly be designing your ship with however many lasers and missiles and such. It has a small clash-like component — builders, generating gold and energy, stealing, upgradable vaults — but the game is old-style 1-on-1 spaceship battles.
Star Squad seems to be inspired by that, but is more clashy. You get a limited amount of rooms, unlocking in clash-like Town Hall style, with plenty of space to arrange them on your spaceship. You have an even more limited number of crew, and only they can fire weapons. Suppose you have 2 lasers rooms and 1 crew. One laser can fire. But when it’s destroyed, the crew member walks to the other. That’s more interesting than it sounds since missiles have an area effect. Fighting another player is still just a 1-on-1 spaceship battle, but it’s more active.
It borrowed the map idea from Boom Beach, as so many other games did. You upgrade a radar, which allows you to see more spaces around you, which have more and stronger enemies and special stuff. They did a nice job copying the computer bases. These are allowed to completely break the rules, since it’s fun. One of my favorites computer ships has only weak lasers and 2 crew to fire them, but there are 12 laser rooms. Every time you blow up a laser, you get a break as she walks to the next. If you can arrange it, a very long walk.
