Here is my idea:
Depending on the difficulty, one to three bandit camps would appear on the map,
these camps would be guarded by hostile NPCs, like in the Far Cry games,
the camps would be built of the same materials available to players, they would also be completely destructible,
after destroying all the bandits’ bases, the bandits would stop to appear on the map,
the bandits would be aggressive towards the players, depending on the level of difficulty, their equipment and accuracy would change,
only on the highest level of difficulty the bandits would try to rebuild their camps,
moreover, the bandits sometimes would go on trips to cities, farms and camps in search of resources
if they encountered a player they would start shooting at him,
the player could avoid confrontation by hiding from them
on easy - bandits should only use pistols or makeshift weapons and melee weapons
on medium - pistols, poor quality rifles or shotguns
on hard - sniper rifles, med quality rifles, shotguns, powerfull pistols, grenades, and occasionally LMG
bandits should not be very accurate and should never shoot a player in the head … unless the player sets their accuracy differently…
I think that such a rich NPCs system would enrich the single player mode.
If these ideas were implemented, the collection of firearms and explosives on the single player mode would finaly be useful.
Of course, all the functions listed above should be completely configurable or even optional.
I realize how difficult it would be to implement this idea, but I’m sure that it would significantly prolong the life of the game.
That’s it
if you have any additional suggestions I will gladly hear them.
