The few enjoyable moments in this mod (such as the stealth sequence) were completely negated by the horribly executed final boss fight. It is possibly the single most frustrating sequence I've ever experienced in a video game, and I refuse to believe the person who designed it has ever played a video game in their life, much less a Half-Life game. But I powered through it! In hard mode, even! Got the achievement and everything. Thought it would be worth it for Entropy: Zero 2. It was not!!
