I was in my local mall wasting time while my mom was trying on clothes. I went into Electronics Boutique to check on prices. I noticed Half-Life: Game of Year for $20 (better than $30). I saw Counter-Strike for $30. I asked one of the people working there what is the difference between the two. Was Counter-Strike an addon to Half-Life?<br> <br> He told me that Half-Life was a single-player or multi-player game. He said that Counter-Strike was not an addon to Half-Life, but was a separate entity and I don't need Half-Life to play Counter-Strike. He also said Counter-Strike was a multiplayer game. But I forgot to ask him if I could play Counter-Strike as a single-player game or practice against bots. So, my question is: can I?<br> <br> Thanks.
