Found It

The robot troops keep coming. They seemed to be spawning from nowhere and suddenly appearing at crossroads or in front of them.

The number of robots in one troop is also increasing. At first, they only numbered twenty, then increased until finally one troop was filled with fifty robots of various shapes.

Now, the troops they were facing had five large robots armed with canons and miniguns.

Meanwhile, the small robots that looked like metal human skeletons no longer only used rifles.

They also now wore swords that seemed to be made of condensed light. The color of the sword is also red, like all things that an evil robot should have.

So, now they're getting harder to handle. Because they can do a melee attack.

*TANG!*
