TF: Deviations is terrible by the power of condensed "meh". The Beast Within is terrible by the power of "WTF I read!?" Different kinds of bad. But they both feel like fanfics.
There's synopsis for the Beast Within on tfwiki. Otherwise it's hard to explain. It's as terrible, but does it in a different way. Dunno... Deviations makes you dissapointed and upset at spending money at it, the Beast Withing makes you facepalm hard enough to give a brain damage.
I'll have to compare them. I wonder if there's a scan somewhere...I sure as hell am NOT taking any chances after wasting $4 in THIS piece of crap.
