Keep playing for most of those points. The game does stay fairly linear throughout, although there are plenty of secrets to find.
Ammo is kept low to force the player into using the chainsaw, which now always regens at least one bit of fuel to use on fodder enemies. You can upgrade the ammo levels as you go and becomes a bit more generous.
Blood punch is a beefy melee charged with glory kills, as well as the dashing that comes pretty soon into the second level.
The first level is slow, but meant to introduce you to the basics before dumping everything else on you. Trust me when I say once it gets going, it GOES.
Playing on Ultra Violence, it feels considerably faster overall than 2016. The monkey bars, jump pads, and dashing really lets you get around a place pretty quick.
