Oxygen tank pakt uit met een review van Opposing force, je weet wel die leuke add-on voor Half-Life.

Conclusie:The multiplayer aspect of the add-on only includes vanilla deathmatch (just like Half-Life) and some of the maps have been designed by some of the best mapmakers in the industry (Levelord for instance). However, Opposing Force's multiplayer deathmatch just can't compete with the new breed of DM-only games starting to surface now like Unreal Tournament and Quake III Arena, who have perfected the art of deathmatch. The single player game is definately the highlight of Opoosing Force. Overall, this expansion pack is a great addition to the Half-Life universe and a must-have for gamers that have been craving for more ever since they finished the original Half-Life.
