Far Cry 5 is coming out in about a week and details about the game are pouring in. As Arcade editor is supposed to have all the in-game assets, it is also supposed to have all the guns involved in Ubisoft's latest outpost capture simulator.
Weapon lists are leaking left and right since reddit sleuths are at it again. People are posting Far Cry Arcade resources across several threads including galleries and videos. So far it seems like the actual list comprises of only a handful different weapons from each of the categories - handgun, SMG, shotgun, assault rifle, sniper rifle and LMG. There seem to be only four assault rifles, reskinned in different ways to give players an illusion of a wide roster.
Ubisoft appear to be compensating for the small weapon roster by adding different skins to the existing ones. It makes sense that a cult would customise their weapons with their symbols or that you would find a weapon painted as a USA flag since that's where the game takes place.
On the other hand, it doesn't make sense that you will find an AK painted in some weird tiger stripe pattern in black, grey and fluorescent green colours. These can be previewed in the embedded post below.
Handgun category stands out and has actual variety with a pile of different revolvers. It is still possible that not all weapons have been added to the game, as Ubisoft are doing their finishing touches a week before its release. There will definitely be more weapons added through post launch content.
Another issue when it comes to weapons is from another reddit post. Weapons will be unlocked by game progression, as you build your resistance group. Resistance will have several levels and as seen in the picture below, you will have to level it up in different regions in order to unlock more.
Far Cry 5's trophy list has also been leaked and can be found here. Trophies don't seem to be grindy and are pretty straightforward. Author of the list noted it should take 20 to 30 hours to complete them.
