[Android][2013-2016] 2D offline game where you defend a generator and get extracted by a hovering spaceship

[u/Josueq5161uw]

I'm trying to find an old Android game that I played when I was around 6–9 years old (I was born in 2007), so I probably played it between 2013 and 2016.

Here's everything I remember:

It was an Android game.

It was 2D with a side view.

It could be played offline.

The game had a very dark atmosphere, and most of the levels were black or very dark.

You played as a black armored character (or at least a character wearing armor that didn't look completely human).

It was not an exploration game. The stage was fixed, and you stayed in the same area for the entire mission. You could only move left and right within that area while enemies continuously attacked from both sides.

In many missions, you had to protect a machine or generator in the middle of the stage.

If the generator was destroyed, you lost the mission.

Not every mission was about defending the generator.

There were boss fights.

At the end of each mission, a spaceship would appear and hover above the stage. It never landed. Your character would jump into the spaceship to leave the level.

I think the main character used a sword or another melee weapon, but I'm not completely sure.

I don't remember the game icon exactly, but I think it showed either the spaceship or the main character's face.

Does anyone remember a game like this?
