    HUGE NEWS FROM MYGRANDFATHER GAMES

    I’ve got a bunch of big news to tell you all about!!! First off I would like to thank everyone for their support. It means a lot! Now for some cool Announcements!!! - New Game Coming Out! Hell of a Birthday comes out February 21st 2025 (THAT'S BASICALLY NOW!!!) IT’S YOUR BIRTHDAY!!! and nobody came to celebrate with you… Hell of a Birthday is a First-Person comedic horror game where you play as the Birthday Boy trying to survive your special day. https://store.steampowered.com/app/3416450/Hell_of_a_Birthday/ Future Games For 2025 (Store pages coming soon!) - Gordy - Gordy is currently in development! The game takes place in the woods where you befriend a feral human Gordy The Gorilla but there's something wrong with these woods and maybe something wrong with Gordy or his teacher. Taking place over several days you’ll descend into madness. While this game will have some comedic moments I’m hoping this will be the scariest game yet! - Bite Night 2 (Name may change) - Bite Night 2 is currently in Pre-Production! You and your Best Friend Vamp got jobs working at a roadside diner serving all the transient people. Things are great until people start turning up dead with strange punctures on their neck. Super excited for the sequel to Bite Night and I have a bunch of great ideas for it already that I believe will make Bite Night 2 even better than the first! For My Final Announcement - I STARTED A PATREON!!! patreon.com/MyGrandfatherGames - I decided to make a Patreon to be able to connect with dedicated fans more! - I hope to be able to post updates about the games a lot on there to get suggestions and show off development. - Help shape future games!!! I want to be able to include people in the development either by simply answering polls or maybe providing their face or voices to characters! - IT’LL BE FREE. I don’t want anyone to feel like they’re going to miss out on anything if they don’t pay so currently all my posts will be available to Non-Paying and Paying Members...
