I've never finished a Half Life game in my life

...
* I have Half-Life 1 (twice cause one is source version though looks same to me)
* Blue Shift & Opposing Force
* Half-Life 2 and Episode 1
I got really far in Half Life one and the expansions but never got round to finishing em and had to wipe my PC.
Got near end of Half Life 2 during when the rebels begin there counter attack and I was pinned in this building by snipers (have to use nades to take em out) couldn't do that then had to wipe HDD
Episode One I got at least half way and same again with HDD, well I got new PC and put my saved file on disc but forgot about it, god knows where it is now
restarted Half Life 2 & Episode One, I would like to finish one in my life time

. Got that Half Life 2 co-op mod Synergy hoping to try it out soon
