More of the same of the main game, which is a good thing, but there are a few things that bring it down somewhat. Obviously the two episodes here don't end with boss fights in the way the main game's three episodes do, instead you end with a fight against multiple prior bosses instead. That, to be fair, is an issue i've had in a lot of games of this type (looking at Doom 64 in particular) but while I get it it's still a bit disappointing. I think the second episode here is the only proper trouble I had finding my way around levels in the whole game too, which is definitely more a thing of my inability than the game being at fault, but it did diminish my experience a tiny bit. Either way, it's a Doom style retro shooter and I like those a lot, and it took about a few hours to beat in total so it wasn't anything I regret. Worth the play if you like Heretic's first three episodes or just like Doom in general.
