I suppose it was hyperbolic to say the AI was as dumb as it was 23 years ago, but I also guess that's why I explained it a lot better in the review itself. Enemies alternating between running at you as fast as possible or lobbing ranged attacks at you from fixed positions doesn't strike me as intelligent.
I think more advanced AI would be challenging to balance alongside numbers, absolutely, but that doesn't mean it couldn't happen. I finished the game (apart from the boss fights, of course) by running laps through kill chambers until a train of enemies followed me to their Doom. That's the sort of thing I expect from MMOs, not a shooter in this, the year of the lord two thousand and sixteen.
