As always with online games, there are a few kinks that need ironing out of Black Ops 4 at launch. One problem players have already started to notice is in Hardcore mode, which turns on friendly fire and drops enemies with a single well-placed shot. If you team kill, you get the boot. Unfortunately, this also applies for if you put down razor wire at a choke point and one of your dumb teammates runs through it. Currently, it’s probably best to not use razor wire at all in Hardcore. At least until Treyarch fixes it. Ideally, the developer should tweak it so razor wire doesn’t hurt your teammates, even in Hardcore. If not, make it so the player who places the wire isn’t kicked for their teammate’s ineptitude. Hopefully we get a hotfix for this soon. In the meantime, check out our guide for Blackout, the all-new battle royale mode. We also have a list for the best perks to use in Blackout.
