25 years ago to this day, one of the video game industry’s longest-running and beloved franchises was born.

Resident Evil, the series which helped birth the survival horror genre on March 22nd, 1996, continues to enjoy as much – if not more – success today as it did over two decades ago and fans are unsurprisingly celebrating the milestone all across the internet. On Twitter, in particular, many are sharing fond memories of their first foray into the iconic Spencer Mansion as Chris Redfield and Jill Valentine, encountering their first reanimated corpse shortly after walking through its doors.

It’s worth mentioning, of course, that not everyone has been a loyal follower since day one, and given how much the IP has changed over the years, it’s looked very different throughout its history. Indeed, while it’s arguably thanks to Capcom’s continued attempts to modernize and innovate with each iteration that Resident Evil has stood the test of time, there have certainly been missteps along the way (RE 6 being a particular low point), though they’ve been far outweighed by the highs.

In any case, take a look at some of the appreciation posts for yourself down below:

From the Spencer Mansion to Castle Dimitrescu – thanks for opening the 🚪 to survival horror, Capcom.

If you’ve ever talked to me for even an hour you’ve probably heard about my love for Resident Evil.

I’m just really thankful for this terrifying, goofy, action packed series. For Leon, and Jill, and Chris, and Claire, and Ethan. I love RE. Happy 25!#ResidentEvil25thAnniversary https://t.co/Gk9QD0LT2F

As for how Capcom itself intends to mark the occasion, it’s confirmed that today is the beginning of a months-long period of festivities that will continue well into the summer and beyond. April will see the broadcast of a brand new game showcase, with the release of Resident Evil Village to follow on May 7th. All of that’s in addition to several movie and TV projects based on the series currently in the works and you can read more about those over here.
