If you are interested in getting all achievements in Ryse Son of Rome you will notice some achievements requiring multiplayer gameplay (like unlock top tier items, getting level up etc).
Some of are easily taken by finding a partner and play in 6-7 maps of survival maps modes and unlock most of them in short amount of time. What takes most is leveling up you character in multiplayer and along the huge amount of time to find partner it;s gonna take ages to achieve it.


However you can exp your character in solo colloseum mode ( thank you developers ) and the map with the most exp is Revolution.

While you fight in these enviroments you will notice some objectives which have to be done in order to progress into next stages of the fight. Well the second objective in Revolution map requires to man a scorpion and defend a bridge. While you are at it, man the scorpion and then barbarians are gonna come at you in 4 waves. You get down (without killing them with the scorpion ) and fight them via executions. It's easy since most of them are minions with only swords at their hands. If you manage to hold the combo all 4 waves (via pressing R button once the combo/hitts are about to expire) can provide you with up to 150k + the next 4 objectives you have to complete in order to finish the map.

Of course this requires to pick Dianna as Goddess before entering the arena and equip items that provide you with extra exp. Normally after you complete the map you are rewarded with 150k-200k exp but if you manage a very good combo (300+) it can jump into 300-350k exp (about 6-8 levels).

I wise you good fortune in the Grind to Come :D
