Never played an Uncharted game.
Is the actual gameplay really like this? Without a HUD and with constant action going on?
Pretty much.
The series gets a lot of hate on certain aspects (Drake constantly quipping, the high body count), but the gameplay is an incredible mix of third person shooting, platforming, and set pieces. Naughty Dog is truly one of the masters of combining cinema and gameplay.
If you haven't played them, I highly recommend the PS4 collection when it comes out. It's hands down one of my favorite series from PlayStation (Ratchet and Clank, Sly Cooper, and God of War are probably the others).
I was frigging blown away when I saw this demo behind closed doors at E3, and I'm so frigging glad that they decided to release it. I had coworkers so hyped about it when I told them, and now they can watch it themselves. Lol.
