An absolutely fantastic game with great puzzle and FPS components, great enemies and bosses, great dialogue, NPC's, graphics, level design and soundtrack. Even though it's a fairly faithful remake of HL1 up until the later levels it still has a very original feel to it and reminded me in a lot of ways why I loved the Half Life's from Valve.
Everyone at Crowbar Collective and anyone else who contributed to this project did an amazing job, it easily competes with games that have multi-million dollar budgets.
