Been playing Alien Shooter for a couple months now. It’s basically a mobile strategy game where you build up your base and then team up with friends to attack other players. Pretty solid if you’re into that kind of thing.
Here’s what you do: you start by upgrading your base and training different types of troops. Then you can join a clan and coordinate attacks with your buddies. There’s also a single player campaign where you fight off waves of alien monsters – it’s a nice change of pace. And the graphics are pretty good, it runs smooth even on my older phone.
Look, if you’re into strategy games, you’ll probably like this. It’s not perfect – the upgrades take forever at higher levels and it can get a bit repetitive after a while. But overall it’s a fun time-killer and you don’t have to spend money to enjoy it.
