This is my favourite FPS of 2020 thus far. Does that make sense in the year of (our lord) Doom Eternal? It's just that good.

Post Void takes the climactic mad dash sequence at the end of many a ten hour experience and says 'that was the best bit - what if that was it?'
And it feels so good to actually complete a roguelike for once. Post Void is bite-sized in the best ways. Not stubbornly difficult, but not not at all dastardly, upon dying you'll realise you haven't taken a breath for the last thirty seconds. Void's roguelike upgrades break up the experience of a void of air into literal breathable portions in a five minute run. Void is exhausting.
Is it a perfectly-honed, perfectly balanced experience? God no - and no thank you. Halo-esque overpowered pistol syndrome is here in earnest. It's overly accurate and can be almost endlessly fired, but why not? It let me complete a run. Whilst I'm not up to a knife run-level quite yet, the other weapons remain fun to play with. Consider them artificial difficulty!
There are a dozen things I could say Post Void is 'all about.'
It's all about its game feel. It could just be new PC magic, but dispatching foes with headshots whilst aiming backwards during a slide is... easy? Post Void makes this frantic scramble also feel effortless when you're on top of it. I just hope that unlocked frame rate update is possible for extra slickness.
It's all about its fever pace. Post Void is actually a game of survival. You have to navigate a fine balance between killing to replenish your ever-depleting health reserves, avoiding enemies carving away yet more, and making a jumping/sliding beeline for the exit. This pace is uniquely married to its music. Its one track dovetails perfectly, but replace it with the official unofficial soundtrack (https://open.spotify.com/playlist/5U5EZgDNJ8HGHdVebHUD3A) and Post Void becomes transcendent.
It's about its goddamn aesthetic. This is what hell must look like - and it's heavenly. Winding corridors and nonsensical rooms of unholy sensory overload and visual noise. Stylish to the extreme.
It's about its leaderboards. That's not my scene exactly. I'm just happy to survive a run. The determining equation revealed on the forums is sufficiently deep to support an interesting scene here, though.
I'm a big fan of any ultra-budget, bloatless slice of sublimity. Post void delivers the FPS as pure experience. Bursts of breathless near-perfected audiovisual and gameplay consonance in a guiltless package. Nothing more, nothing less.
