Apesar de eu ter sofrido muito jogando ele, concordo que é uma ótima expansão do primeiro jogo, trazendo uma perspectiva bem legal de Black Mesa, com novos inimigos, armas e tudo de bom que o jogo original traz

Even after replaying and enjoying the first Half-Life more, I still think this is the better game overall. It may not have had the same impact and importance the first game had, but in terms of enjoyment factor and consistency, this easily takes it. Also helps that this game did an amazing job of expanding upon the world of Half-Life and showed it from a different perspective. Bring back Adrian Shephard
