I agree that invincible buildings would be a good feature for the 2.301 trainer.
If I remember correctly, the CheatHappens 1.51 trainer for the original CoH had that feature.
When it was not included in the later trainers I assumed that one of the many patches "broke" the invincible buildings feature.
Now a real challenge would be to have the invincible buildings feature that would work on base structures, and world structures (houses, chateaus, shacks).
I'm definitely satisfied with the current 2.301 trainer as is though.
As for cheathappens, its hard to beat a one-stop-shop with guaranteed virus-free trainers, massive and responsive technical support, and featured guides. (strategy guides)
GJ CH team and keep up the good work!
Yep - that pretty much sums it up.
Well worth your hard earned cash because they're working hard to earn it too.
