Valve's next game is an Overwatch-style third-person hero shooter named Deadlock, a new report has stated. Details have…
The PvP experience itself has actually never been in a better spot imo in terms of content delivery and balance cadence
That's more of a Counter Strike clone. The "abilities" are more akin to CS utilities like smokes and flashes than they are to Overwatch characters. The rest of the game is pretty much a direct copy of CS.
It's actually a technical problem - Valve is running 1 bit computers that, due to binary origins, can only represent 2 states. They'd love to release hl3, but that would require coming up with the whole new architecture - at least doubling up to 2 bit cpu. Imagine the headache of adapting all the toolchain to build the game!
Valve could trivially circumvent this limitation by using a multi-precision library such as MPFR
See, that's a common mistake - MPFR library is a C library for multiple-precision floating-point computations with correct rounding. Valve is, unfortunately, still stuck to integers. Their floating point appears to be functioning correctly as they've managed to avoid kernel panic releasing hl2e{1,2} - you can look at that as floats 2.1 and 2.2.
what is a hero shooter and what makes it overwatch-style?
I'd think tf2 would be one.
You'd be correct about tf2.
I would define a hero shooter as having Moba style characters in a Counter Strike style environment.
