Regarding the Trainer, Unlimited Health, Easy Troop Kills,....
Obviously, I believe trainers, hacks, and cheats should always be acceptable in a Single Player setting. That's just a simple fact.
However, regarding this specific game, I think there might be a small problem.
The problem here is that events in the single player modes this game offers DO have what could be considered either a direct or indirect effect on multiplayer.
The reasoning for this is that completing both missions and survival solo still awards the players with credits that can be used in multiplayer. And its not exactly a small amount that you can earn either.
I used this trainer with Unlimited Health and No Overheating to complete all of the missions and one of the survival missions, all on Master difficulty, and accrued around 25,000 credits. And early on, that can net you quite a bit of items to buy for multiplayer, i.e. blasters, cards, appearance customizations.
I suppose I just want to bring this up to get the trainer devs' opinion on this. I'm sure no one wants to get punished for using these, so I just wanted to bring this up now, in the case that something like that might end up happening in the near future.
