I finally installed HalfLife 2 : Episode 1 which I bought in October 2006.
Exactly after an year I installed it and started playing the Single Player missions in HL2 : Ep 1.
Along with HalfLife 2 : Episode 1, I got
- HalfLife 2 : Deathmatch
- HalfLife 2 : Lost Coast
- HalfLife 1 : Deathmatch
I just completed the first level before posting this here. I’m planning to sit in the night and complete the game over the next week.
