10 Infuriating Video Game Cliffhangers You Didn't Realise Have Answers

In Sly Cooper's fourth outing, the mischievous racoon must ally with his ancestors to stop mad scientist, Le Paradox, from taking over reality. The showdown takes place inside a rip in time, with Sly emerging victorious.

However, Sly goes missing after the battle, causing his allies to speculate what happened. Despite searching high and low, his comrades can't find their furry friend. But by collecting every trophy in the game, you can unlock a secret ending, revealing Sly has been transported to Ancient Egypt.

With an ending like this, anyone would assume Thieves In Time was teasing a fifth instalment. However, Sly seemingly vanished off the face of the Earth, since we haven't seen him in a decade.

Although Sanzaru Games intended to continue this story, it would've been in an expansion pack, not a direct sequel. In a 2019 interview with the game's director, Matt Kramer, he explained the DLC would have Sly's squad travel to Ancient Egypt to retrieved their partner.

“That was always the intention, then we never got to finish that out. The team at Sanzaru, we have the story, the whole episode done on paper form, but we would love to come back to that world. I hate leaving him there. It’s the question we get the most."

Sanzaru Games hoped Sly Cooper could have a resurgence of interest after the release of the film and tv series adaptations. But after these projects were cancelled, Sly Cooper hasn't had enough buzz to generate a follow-up.
