Slave Zero is an old game so the graphics and gameplay mechanics are definitely dated. But I don't know any other game that lets you stomp around a cyberpunk city as a giant robot. The game does a great job of giving you a sense of scale with all the little flying cars moving around your feet as you jump from building to building. I still enjoy it.
If you've never played Slave Zero, here's a trailer. It's available on Steam for $7 but if that's too high a price, it regularly goes on sale for $4.50.
Also, I refuse to accept that the new game Slave Zero X is actually a prequel to Slave Zero. I don't care if this company bought the rights to Slave Zero and claims it's in the same universe. A 2.5D ninja beat 'em up is nothing like jumping around a cyberpunk city as a giant robot.
