I've decided that Hard Reset, as minor and limited as it is, is a true retro-FPS.
Does it blend old skool simple / fast gameplay with modern production values??
Does it actually have a theme, purpose, design, satisfying weapons and a decent bestiary??
Yes to both.
It has many issues: Movement is a bit sluggish, enemies are a bit bullet-spongey, almost all the cool architecture is a pure un-visitable backdrop, it's very arenay in places and quite 2-D in others, and if you care about such things the inter-mission story / dialogue is beyond terrible, it's also pretty damn short including the DLC.
But I had fun with it. The double weapons and their plethoric upgrades are actually nicely done and fun, the enemies at least have a theme, the backdrops are really cool and the overall graphics are good.
