Where is the chaingun commando and Spider Mastermind? The Mastermind was in the last game sure but they could have brought it back. The commando was the only other missing enemy.
The Spider Mastermind was around in the form of the Arachnotrons. The lore quite literally states that salvaged organic matter of the Mastermind was used to make the little bastards. Sure, the actual boss isn't around, but DOOM 2016 was more a straight update to the original DOOM while Eternal is largely the same with DOOM II with more creative liberties taken.
And the chaingun commandos were probably left out because there's already a ton of enemies and one more wouldn't have made much of a difference or really even have been noticeable from the regular soldier since the game seemed to have a very fetishistic attachment to dropping in Arachnotrons in
every battle more or less from the literal start of the game.
The Unmakyr was underpowered. Very sad.
This I will agree with. It's supposed to be stronger than even the BFG, but the BFG will kill anything in one shot, whereas the Unmakyr weirdly has trouble doing an equal amount of damage to heavies within the same time frame and ammo consumption. It looks great but it really doesn't have a role to fill that the BFG doesn't already do better.
And it didn't have the one thing I wanted, even if it was done via cutscenes, I wanted to see a suburbia overrun by the demons. Instead, we got a futuristic world post-demon invasion. Which is still cool but I wanted to see the invasion as it happened and a Cyberdemon or Spider Mastermind stomping around the ruined homes. Maybe we'll get that in some future DLC?
Unfortunately, the game already takes place in the future given Mars has a power plant outpost already set up, meaning interplanetary space travel has been achieved and thus you were going to get the futuristic world anyway.
And to be honest, the demons of hell aren't really all that different from an alien invasion if you ignore the lore behind their existence and thus we've gotten "aliens invade suburbia" quite often.
The low-key ending didn't bother me. I like to think that from Doomguy's perspective, erasing entire realms out of existence and saving Earth from a universe-busting disaster is just another day for him - there's no true ending because Hell is always going to find another way to fuck shit up. He's been through enough games and backstory to know that.
Regarding Doomguy, the ending was fine...but there was a LOT more going on that simply was left open without being addressed. I mean, what exactly is Hayden's end game? He's sort of been the guide of the rebooted DOOM universe for Doomguy (especially given what becomes obvious from the lore regarding his relationship with Doomguy) but he clearly has an agenda of his own and he doesn't even get a remark about what to do now that the Icon is dead and the Khan Makyr is out of the picture, too?
Still, if we're talking about niggles with Eternal, one of my genuine complaints is that the ending credits is just photos of people from the dev team smiling at the camera; Doom 2016 had a bunch of panning shots that occasionally got creative (like having the Doomguy doll take on a Pinky). The post-credits scene salvaged some of the disappointment, but I still wanted to see more of that.
I wholeheartedly agree, the DOOM 2016 credits were worth the price of admission alone for that game (Granted I bought it on sale about two months ago so I paid like, $10), but Eternal...you had ALL those new assets and the best you could do was
that? Not even some funny shots of the Marauder flipping tables or something?
