Even after the 25th anniversary update for the original Half-Life, this mod is still a must-play if you're looking for a reason to replay the original but want to spice it up. Revised gunplay and enemy AI make it really refreshing on a replay, and the added visual enhancements and slight level edits make it feel different enough to be a reasonable alternative. The enemy count was increased too, this is great if you're looking for more of a challenge, though it can be annoying early-game when there's more enemies than you have ammo.
