The Epic Games Store is doing their annual daily giveaway leading up to Christmas. As per usual, I probably won't be mentioning every game from Epic here, so be sure to check it out every day for the duration of the event, which usually lasts a week or two.
Today's giveaway is Vampire Survivors. It's a game that looks pretty terrible in screenshots and maybe even videos, but is surprisingly fun to play. There are few games in my Steam library that I've played for more hours than I have played Vampire Survivors. In other words, even if you think it's not for you (as I did when I first heard of it) I recommend checking it out and giving it a try since it's free.
