Duty: Best Faction overall. No weakness. Saviors of Humanity.
Loner: Many of them and nice. Also better fighters than Bandits
Clear Sky: Small in number, but look the coolest and have a large variety of weapons.
Ecologist: Friendly to everyone in the zone, even the mutants.
Military: Tough soldiers and good Russian equipment, but tends to prey on everyone else thats not Eco or Duty
Mercs: Like the military, but smaller in number and use Western weapons.
Monolith: a bunch of braindead cultists who rely on zerg rushes and cant get past a roadblock guarded by a couple of Potheads
Freedom: Pothead antifa Tankies who like Nato weapons and are always trying to have s*x with Bloodsuckers. Stashes are full of H*ntai.
Bandits: Worst faction period. Similar to Cockroaches but taller, stupider and shout CHEEKI BREEKI while they blow themselves up with a badly placed grenade
