On a regular basis, PlayStation publishes trailers for games of all shapes and sizes on its YouTube channel. If you're interested in indie titles or smaller projects, it's worth checking the page every now and then. The most recent trailer is for a little game called Savage Halloween, a retro action platformer based in a spooky world of pumkpins, skeletons, and clowns. The video's title indicates it's a trailer announcing the release date — but, er, there's no release date to be found. Now that's scary.
Don't worry, we've got your back. Savage Halloween is actually out right now, having released yesterday, 15th April, for PS4. Costing just £3.99 / $4.99, it might be worth a try if you're in the mood for some Halloween-themed fun. It doesn't look to be doing anything particularly new or exciting, but retro heads may well get a kick out of it.
Anyway, hopefully videos named "Release Date Trailer" will actually state the release date, moving forward. That seems like a smart move from where we're sitting.
