What makes Infinite Warfare the best campaign this gen?
I'm not exactly on the "Best" campaign bandwagon, but Infinite Warfare is quite enjoyable.
The space setting is unique, the space combat sequences control especially well and look incredible, there is a wee bit of post-mission engagement back at base...not much, but some side-activities and bonus missions between major sorties to break things up a bit and add some macro-level optional progression fluff to the mix. Oh, and the characters are actually pretty well developed and very memorable. By the end, I felt attached in a way rarely one does in an 8-10 hour fps story.
As a game though, its fully more of the same. Linear, corridor shooting with waves of enemies and not much thought or tactical approach. I finished it on veteran difficulty and didn't have much issue. At no point did anything gameplay-wise really stick out or differentiate from the usual whack-a-mole feel of these spectacle games.
As an aside, I'm currently playing CoD: WWII and feel the return of smoke grenades, squad abilities, health kits, and multiple engagement options(even if basic) have actually added quite a bit to the experience that other recent CoD games have lacked. It's just as linear and cinematic, but the flow and my input feels more active than just reticle aiming. Not even sure why it was divisive, it feels like a nice return to old CoD.
Modern Warfare 2019...a few missions in and its more of the same. Gorgeous, but bombastic and not a lot going on in the design flow. It's a blockbuster production absolutely, but not doing much beyond impressing with its tech and audio.
