Video and fan-art mash-ups of Team Fortress 2 and Overwatch are starting to appear online.

When Blizzard revealed Overwatch as its brand-new IP at Blizzcon this year, I figured I wasn't the only person who noticed the game's distinct similarity to a certain war-themed hat simulator. The internet has been quick to react, and has already produced a variety of video, and fan-art Team Fortress 2/Overwatch mash-ups.

First up, check out the YouTube video to the right from user RizkitsunΣki, which substitute's the sound from Overwatch's reveal trailer for voice-overs and sound effects from Team Fortress 2. It's almost too much of a coincidence how well the TF2 classes slot into Overwatch's efforts.

Next, for an even more striking comparison, artist Silsol has made these stunning fan-art mash-ups, showing the Medic in Mercy's outfit, and the Scout and Tracer wearing each other's clothes. Check them out below:

While it does have a bit more of a sci-fi twist, these fan comparisons make it quite obvious where Overwatch draws its inspiration from. Blizzard are no strangers to taking a popular game and putting its on unique spin on it, and so far at least (see: World of Warcraft) it seems to have worked out for them.

Let's hope that Overwatch has enough to keep it distinct from Team Fortress 2, otherwise my money is just going to keep being funneled into crate keys.
