Doom 2016 (from here on referred to as DOOM) takes everything you loved about the classic Doom 1 & 2 and turns it up to 666. The game is fast paced and encourages quick twitch timing for speed runs. However, the game is very forgiving, even on Ultra-Violence (very hard). You get enough ammo for each battle. You're never unprepared for what comes next. It's your skill that makes the difference. As difficulty ramps, the game teaches you what you need to know, then throws you in to apply it. Mastering the fundamentals and learning enemy patterns is key. If you die, it's because you need more practice. The bosses include the Cyber-Demon and Spider-Mastermind. Both have patterns that are read, rinse, repeat. Once you know the patterns, fighting them isn't that difficult. It's the heavies that cause problems because they're often paired with hordes of enemies. Balancing the fodder with the heavy is key to success. Like Doom and Doom 2, DOOM features tons of secrets. John Romero and his team had the philosophy that "If you can see it, you can get to it" for Doom. DOOM follows that mantra. I didn't find all the secrets, but the ones I saw and searched for were obtainable. DOOM isn't without its flaws. A fully upgraded shotgun is all you need for most of the game. The face that you can carry a single weapon to victory is a slight let-down. Contrastly, Doom Eternal requires players to use certain weapons on certain enemies. Given the choice between these two, I'd rather let players choose the weapon they want over forced weapon switching. DOOM is a fast paced, shooter that is fun to play. While Doom Eternal takes more of a platforming approach, I prefer DOOM's flat level design with a higher focus on combat over platforming. I have purchased DOOM (2016) on PS4, Switch, and now Gog. To buy a game for multiple platforms says a lot. I would STRONGLY RECOMMEND this title.
