Amazing re-entry
An extremely tight soft-reboot to the franchise, with almost nothing unnecessary tacked on. Gunplay, movement, level design and absolutely the plot and lore are all excellent. Obviously the highlight is the gameplay, but the plot and lore really should not be missed, with fantastic usage of "less is more" and "show don't tell" writing techniques that really elevate the experience.
There is definitely some clunkiness as the game goes on, with slightly rougher edges in the length of some later levels and boss fights. Additionally, many players are likely to favour some weapons over others which may feel like leaving fun on the table, and will rub up against some of the occasions the game tries to encourage more diverse weapons usage. This is further compounded by some clear "best in slot" weapons and weapon mods, especially in conjunction with challenge abilities - though the latter is really a reward more than anything.
Overall, Doom 2016 is probably one of the best single-player FPS games of all time, and I encourage anyone to buy it whether they're an FPS fan or not.
