The best game in the core series.

The sequel went from 9th generation of FPS (sawtoothed arenas with spawning enemies) to being an action game. But together with new and diverse level sets it only made game less of a repetitive grindfest (FE). Also new story and direction finally tied that whole mishmash pile of enemies into cohesive world in that rare setting of cartoony zany vinegret (like alice in wonderland, or Heavy Metal: F.A.K.K.² in this case). And unlike BFE it doesn't turn them into a grey-brown color-corrected unremarkable dullness.

Story is a generic post-modernistic referential "deconstruction" with extremely dumb jokes which are delivered rather well and usually funny. But while having good enough mechanical catharsis with the last boss, plot-wise it just tells that main antagonist got away, ((( I R O N I C A L L Y ))) point its finger on it and says "OH YOU GUISE AIN'T THIS DUMB, AIN'T ME SO HIP AND COOL TO POINT AT IT?".

Still, technically it is a 9th generation FPS in it's core gameplay and is mostly the same as first games, just with turrets, vehicular sections and overload of cutscenes (and loading times between them). It mostly behaves as expected and some guns are rebalanced to be more pleasant and useful. Also this game has one of the best shotguns (which is also totally balanced) i can remember (first place being taken by Ex Machina shotguns, which are that way only by happy coincidence of several minor bugs, though).
Well, hope you liked bulls and kreels from the original, because those types of enemies make about 50% of them all, even some old ones have this new behaviour. The other 50% are annoying flying monster; everywhere. It kinda gets overboard on the latter levels, but is still manageable.

When it was released i didn't like the new face of sam, but now i think it's kinda better that way — it has the most character and is most recognizable. BFE sam is also beats the original version. Most music is kinda great, but totally ruined with dynamic mixing.

Technically game is mostly fine, it works In UHD UWS Surround after editing of .ini file and runs stable. But sometimes mouse behaves strange and feels off or laggy and game sometimes can corrupt your save file so it would crash the game on read or write, so better have bunch of them and do it often.
