Croteam experiments with the level design on this one quite a lot, and it usually doesn't pay off. I played the first 2 levels on Normal and that difficulty is still too hard for me, yet Easy is too easy (which is an issue with the other games in this series that I've played). The approach taken by this DLC seems to be placing more of a focus on fewer hordes of enemies and more heavy enemies that fire at you from a distance, encouraging the use of the sniper rifle much more. The fact of the matter is that staying at range and chipping away at enemies isn't nearly as fun as trying to back away from a swarm and cleaning them up with a big arsenal of weapons.

I haven't played the base game in a while, but this DLC was really underwhelming to me. It took me a little bit under 3 hours, but I must've spent about 1 of those wandering around trying to figure out where I was supposed to go, two of the three levels are terrible at pointing the player in the right direction and this killed the pacing for me. The game also loves to put so many annoying enemies at distance who just shoot homing projectiles at you, this made me feel forced to play from behind cover rather than in the thick of the action, which I find boring. It also seems to emphasize the use of the sniper rifle too much, I would've liked to use other weapons but the game mostly just gave me sniper ammo. It may also be worth noting that I played this using Serious Sam Fusion because it tends to have better performance than the original Serious Sam 3, but I'm pretty sure this also causes the AI to sometimes get stuck on level geometry which isn't good. I just wish that they would've just went all out on the action, that's all I want from Serious Sam, but it's not that bad I guess.
