I’m finding it kind of hard to believe there’s so many Half-Life fans here who have never seen/played/heard of the mod ‘Sven Co-op’. It’s probably the most developed mod for HL1 (bar TFC?) and provides literally 100+ hours of fun. For the past 2 years the mod has been rather… dead, however in the last 6 months they have updated it to the new version (4.0/4.07) which is a VAST improvement. Basically they’ve overhauled the NPC’s (New models/AI/Attacks) and improved upon the weapons with again new models/animations/sounds.
There is a somewhat active mapping community who create some great maps involving objectives/killing enemies all with the help of your friends/randoms Online.
Like I said 100+ hours of fun, keeping your mind off the release of BM. Really, I recommend it.
Edit: 100+ hours of fun if you played version 3.0 with the large amount of maps.
Did I mention full HL1 main storyline online cooperative with full HD models?
If you’ve already played the mod I’d love to hear some stories or praise from the game
