make sure the pudding isn't too soggy but that just ruins everything
Bricks hurt more, bottles make more noise. I'm on #TeamBottle because more often I was using the throwables to lure enemies into planned traps or headshots, or just distract them to get a clear path to the exit, than for offense.
Higher difficulties, survivor specifically, is Team Brick all the way. It does everything the bottle does, but even allows you to preserve your melee weapon, since the brick is a single-use melee kill itself.
The better noise attraction of bottles is good, but on scavenger, with resources so low, it's hard to ever choose a bottle over a brick.
