One of the few nitpicks I’ve had with this game is whenever I play Flood, the infected can always kill me because their thruster pack is too fast and they somehow kill me from the grave. I think if you decrease the distance or speed on the thruster, the game will be more balanced 
It can be a little jarring at times I suppose but I still find it hilarious when they run into a small rock and go flying off the map.
Have you used it in regular multiplayer?
It’s worthless. At first I thought I wasn’t holding it down long enough. Right now, it’s literally the worst AA in the game.
It’s fine to me. Just need to shoot them at the right time.
Yes, thruster pack in flood can be annoying since you can kill the zombie then they infect after they have died but if it wasn’t for the thruster pack the zombies would get wrecked. And by the way I love the thruster pack in multiplayer, it’s an easy way to avoid being killed if used correctly.
The Thruster Pack is extremely overpowered in Flood.
I’m constantly killed by Flood that hit me with their claw when they aren’t even looking me. All they have to do is Thruster Pack past me while swinging and it hits me.
