Doom Eternal knocks it out of the park in pretty much every category from a gameplay perspective. Adjectives that describe it: FAST, FLUID, CHALLENGING, SMART, STRATIEGIC.
Every weapon, mod, ability, and piece of equipment is both powerful and purposeful, and FUN! Glory kills replenish health, chainsaw supplies ammo, flame belch adds armour. There are AOE weapons, precision weapons, and strategic weapons that all have their place when battling the game's outstanding enemy variety. All this combines to improve the players skill over the course of the game and stay challenging throughout, with never a dull moment nor difficulty spike.
Eternal's story answers questions left by it's predecessor while telling a pretty good one on its own, all while never taking away from the action. It's epic, well paced, and easy to follow.
The game also includes a creative multiplayer mode that has surprising levels of depth and strategy. Battle Mode has two demons against one slayer and gives players lots of gadgets, tools, and abilities. It's well balanced and can rise to the same level of intensity as single player and even further sometimes! Unfortunately, it seems to be using peer to peer servers which can cause some nasty rubber banding and connection issues. I hope they can smooth these out soon. But when it's working well it's f--king awesome.
This is an easy game of the year contender and cements DOOM as the most ledgendary and iconic FPS franchise ever. 30 years ago it put FPS's on the map, and now it's back on top. Buy it now!!!
