So, if you've ever played Hexen and thought:
MAN, this game is too easy with its switch hunt, puzzles, cryptics, monster respawns and mazes, and I want something HARDER

Then this addon - is for you
Unfair monster teleports - check
Even more items to insert in things - check
More puzzle switches - check
More secrets needed to unlock to have progress - check
Some bosses return - check
Harder battles - check

But to be fair
The plot makes no sense at all - your already dead masters - are back - again. And they want revenge - so we about to kill them - again

The level design is still pretty vague but at least now there's way less going back in forth between locations - so its way easier to understand what to
Also, lots of shaking in frozen dungeons - not a fan of that.

No new textures or visual upgrades

No new weapons or monsters or music, pretty much everyting except for some new quest items is reused

Therefore, not very replayable

Final score - 3.4
Pretty bad, feels like a cash grab, although some improvements in gameplay loop are commendable.
