[AC Question]

The game's logo had an angel and horse on it,
The game's basis was a rpg.
An angel was in war, and you fight enemies, and you can either hire the enemy or kill them.
You would level up per several kills and evolve
Your minions would level up, and evolve, including the angel
It was a long game, and really hard.
If you angel died. You had to start over again
I forgot the name. Any help?
