Traveller's Tales seems to be hinting that LEGO Jurassic World is indeed a real thing.
A screencap taken from the closing credits of LEGO Batman 3: Beyond Gotham posted on PCgamesN shows a T-Rex climbing a building next to Batman and Robin.
Back in September, promotional material from Toys R Us mentioned a “Lego Jurassic World video game contract” was in the works.
While neither LEGO nor TT Games has confirmed the game is in the works, with today's revelation, all signs seem to point to yes.
You can see the hint for yourself in Let's Play video posted below from YouTuber Throneful. It happens at the 26:35 mark.
LEGO Batman 3: Beyond Gotham released yesterday in North America.
