After playing months of M1-4, I can honestly say today is the first day I ever actually noticed a modifier during gameplay. I used to forget they even existed for weeks at a time, until I accidentally noticed them listed on the map screen. Then I’d soon forget about them again.
That’s because they were usually uninteresting math tweaks that amounted to ‘this aspect of the game is slightly more/less bullet spongey’. There was nothing ‘mayhem’ about them.
Some of the 2.0 modifiers I’ve seen today though have actually been interesting and fun, and have kept me on my toes or encouraged me to alter my playstyle. So far a definite thumbs up from me.
