The modder has also released a trailer for his co-op mod that you can find below. Still, it’s worth mentioning that the modder aims to add more improvements for cooperative mode via new updates.

Do note that this initial version does not contain the final boss (Nihilanth). Half-Life: Coop version 1.0 is only 56MB in size and you can download it from here. As such, this is a must-have mod for all purists Half-Life fans out there. In other words, the objective of this mod is to be compatible with the servers of Half-Life 1 and keep it as vanilla as possible. As its title suggests, Half-Life: Coop allows you to play the campaign of Valve’s classic shooter in co-op mode.Ĭontrary to other co-op mods like Svencoop or DC coop, Half-Life: Coop does not change important aspects about the game. Modder ‘Hiems’ has released a pretty cool mod for the first Half-Life game.
