Having removed the PSN requirement, I can re-recommend this game, however with some caveats.
The core gameplay is extremely fun, and really makes you feel powerful but not invincible, encouraging teamwork and cooperation. It's possible to solo on lower levels, but the meat and potatoes is in the coop gameplay.
There are issues tho: It is technically possible to get the premium currency in game, but it's a massive grind, encouraging you to get the battle passes. These would be fine, if specific powerful weapons weren't locked behind premium currency instead of earnable through the main game like the rest.
The other issue is that the developers can't seem to stop Meta balancing all of the weapons and enemy effectiveness. In a PVE game. Where there's no competitive modes. It's just ridiculous and grinds some of the enjoyment you can get out of the game
However the main issue for me is the lack of narrative direction: Starship Troopers (which this game is inspired by but more fascistic in its ideology) had a compelling narrative and characters to keep you invested. This doesn't. The world and universe are cool, but we don't learn much about it directly, nor is much of the fighting for any specific goal besides "Kill the Bug Aliens and Terminator Robots", which gets boring after a while. Starship Troopers Extermination is planning to add a singleplayer campaign, which further highlights the shortcomings of the game's narrative, even compared to Helldivers 1.

Worth getting on sale, but it's a one-trick pony. They captured lightning in a bottle and did nothing with it.
3.5/5

BELOW IS MY OLD REVIEW FROM WHEN A PSN ACCOUNT WAS REQUIRED TO PLAY THE GAME ON STEAM.

(The Playstation Automatons have taken over development and have deployed an anti-earth propaganda virus known as "PSN" straight into your PC device.
The vrius prevents accessibility in most countries and makes your system exploitable and less secure if you are able to access PSN.
Despite this crushing defeat, the bug menace still needs addressing
All Helldivers please report to your nearest Earth Defence Force outpost and resupply with their standard gear for combat.
The EDF deploys!)
