.......no
......yes
I own the game and beat it twice. It feels nothing like Call of Duty. They were going for a more epic, one powerful man overcomes incredible odds type of thing that HL has. It had Ratchet and Clank style weapons, only more serious.
Have you played the game? It's obvious Insomniac was very much inspired by HL and a few other games.
It's also a great damn game. Definitely one of the best console FPS games I've played.
