Quite some time ago, I tried someone else's game that stuck on my mind. It was called Unsynced:

Unsynced - Retro FPS Game by CageMeIn

To describe my experience with the game... it felt like a classic FPS, but it blended some more modern mechanics in an experimental way.

I am promoting this game because:

It seems not to have gotten a lot of exposure despite being a pretty interesting idea.

I feel the idea behind the game is pretty cool overall. It makes for an interesting experience.

Really cool gameplay mechanics. This is a nice combination of retro fps and a modern parkour shooter. Thanks for sharing!
