Helldivers 2 is basically Starship Troopers meets Earth Defense Force and the most fun I've had with a co-op shooter in ages. The gameplay loop and progression is great and constantly rewarding and while I hate the concept of live service models in games in general, Helldivers 2 is easily one of the best and most fairly executed live service model systems I've ever experienced thanks to the devs giving the player the opportunity to earn the premium rewards without actually spending a single dime on micro-transactions just by finding bonuses in the missions themselves and gives you extra incentive to go off the beaten path in missions and explore every planet to its fullest.

Helldivers 2 is far from perfect, it's a very buggy game (Both literally and metaphorically), it has major server issues and half the time you won't even be able to log on and it could use much more variety in the mission objectives, enemies, weapons and locations, but it will still provide you with hours upon hours of mindless chaotic fun liberating planets from waves of bugs and bots and spreading managed democracy far and wide with your boys.

I'm doing my part!
