Last but not least we had to add Neon Shadow to this list. And while this game did cost money in the past, it's now completely free for Android smartphones and tablets.
Neon Shadow is a fast-paced Cyberpunk FPS shooter game. The entire game has that classic shooter feel to it, and you'll surely love everything it has to offer. Again, this game cost money before, but it's free now, so we had to recommend it.
The mission is to save humanity from dark mechanoids who took over your space station and play to destroy the universe. Use powerful weapons to destroy them. Or, play the fun multiplayer shooter modes instead of the campaign. Yes, you'll see a few ads if you're new to the game, but it's totally worth it. If you like shooters, this one is for you.
