I bought Bioshock 2 today, and when using the latest trainer it messes up my weapons and plasmids. I haven't used any of the options to change my plasmids either.
The menu lags to come up too (pressing ESC) and now I'm stuck early on because I can't use telekinesis to move the bar jamming the door gear. Super Speed + Jump, didn't work and increase cash was also broken. Not sure how the Eve and Health work but the Health worked, Eve was so-so.
Anyone else encountering problems during gameplay?
You can always alter the script that allows for replacing plasmids,etc, without a trainer. Just do a Google search for 'Bioshock 2 PC cheats', and you'll get laundry list on the "how-to". It works a treat, but kinda takes the excitement from the game since you cannot die.
I very rarely use trainers, but the ones from here work pretty damn well from the experiences I read.
