Rebel stronghold RP, Lambda calls the shots from a distance and all Union Factions get renamed to rebel equivalents (e.g. UM becomes “rebel medic”, CWU becomes “rebel engineer”, CAB becomes “Lambda representative”). Citizens become renamed “refugees”, and the Combine are masked menaces with nasty surprises at the periphery. There is no such thing as “contraband”, the fragile nature of the area means that everyone should be packing to deal with the Xen wildlife that can and will eat their faces.
Rations become “food bags” with a little stipend from Lambda simply to stave off bartering. The food is usually some form of headcrab meat or worse. Actual rations are a rarity, with higher tier loyalist rations practically unheard of.
Hunters stalk the area just past the barricades. Anyone making a run towards the city’s sewers is either running low to the ground and quiet, or with a heavy escort.
The first 10 minutes of HL2 have been done to death, time for pre-shelling Ravenholm.
