They nerfed the shit out of the sliquifier. They made it harder to chain because people were abusing it, made it more slippery and they did it because of all those people in those spawn kill glitches (galva knucks and the other ones)

They also made it past round 100 it takes multiple shots to get a chain going.

AKA glitchers **** us legit players attempting round 100+

I got to 100 and found out how bullshit it was... quit on round 100 on sheer bullshit of how retarded it was. You run out of ammo so fast and you can imagine how stupid it is to cycle out the sliq during a round especially on solo
