Hiya there,
@STN, @STiNGERR, @unknown_v2, @REPPiN, and others. Please, if you can look into this game, and implement the below trainer options, then it would be really nice. 
Painkiller: Hell & Damnation, the latest version on STEAM. I presume the version would be v1.10, (STEAM 06.04.2014 patch), which includes the DLCs as well, or otherwise.

Though, I really need all the following options to be implemented, as I find this game too hard to beat, as it is very fast paced as well.
. Infinite/Unlimited player health.
. Unlimited ARMOR/shields.
. UNLIMITED primary as well as secondary AMMO (Infinite ammo/no reload).
. 1 HIT easy kills. // I really want this option.
. Ghost mode/Invisible, so that the enemies don’t attack the player. // I really want this option.
. Slow-motion enemies/AI, so that all the enemies cannot move and run very fast. // I really want this option.
. SUPER player speed, so that the character moves fast.
. A FREEZE enemies option as well, if this can also be implemented ?
. Add SOULS and COINS.
Well, that’s it. Thanks for reading. If a trainer can be made, then I would be HIGHLY thankful to you guys. I know you might be hard pressed for time, but just look into this FPS title.
Apologies, for any trouble this may cause, but I’m just giving a suggestion for this game, since I presume we don’t have a trainer yet for this title ?
Keep up the good work. Cheers. 
EDIT: I hope the game’s version is correct, just check it, OK ?
