7/10 - Agree Disagree (1)

I liked the idea of this mod, but as many have stated before, it does fall short on some of the design and gameplay.
THE GOOD:
-Brings you back to fighting the Half-Life 1 enemies! (Vortigaunts, Hound-Eyes, Human Grunts, Apache Helicopters, and those sweet bad-*** blue Vortigaunts)
-Fairly well made weapons that FINALLY aren't the original HL2 ones
-A good variety of dark, enemy-filled, trap-laden maps
THE BAD:
-Not great design of maps (Too many places to get physically stuck in, cover is rare, finding things is not commonplace, ammo for map-specific weapons is scarce
-That annoying sidekick (His speech is at times funny, but having to go back and heal him, as well as him not being a help whatsoever in any situation except for kills at 5 feet away)
THE UGLY:
-The dark is a bit TOO dark, and maps have some issues with lighting, texture, and material placement
-Those damned baby-headcrap carriers. Thank goodness there were only two when I played (Can't see the babies in the dark)

6.5 out of 10. 7 because I sort of pity the careless mistakes here and there. Need some good updates.
-Gameplay is a bit iffy (Guns seemingly jam sometimes, grunts and vorts can fire upon you from exploits in the map, tons of errors in fights like the uber-vort fight and 1st apache fight)
