Anyone tried the Unleashed trainer? If that trainer is having the same problems? It shouldn't be to hard splitting enemie and player up. I don't know what you mean with easy kills Cal, when you inject 1 into the enemie health it's already a One Hit Kill, not sure what easy kill means than. You need to shoot twice than??
I have just tried the Unleashed trainer, and it does make me invincible, but also kinda glitches the boss as well.
It definitely seem that they have done something differently at the Vlad boss.
With the unleashed trainer, even without any easy kill or hit options he goes down to near-dead from the beginning, when you finally get through the laser maze he bugs out in the following showdown.
you can restart there without invincible to fix it, and then he bugs out again at the second part of bossfight where he cannot be harmed by my shots. Using precision aim or the spin attack works but normal shots don't.
After that all enemies are invincible, again with the exception of spin attack + precision aim.
So they're doing a pretty good job, and it bugs out for both trainers, although in each it's way. So i think we can safely put any x is better than y issues aside, it's obviously a problem for the game itself.
