The Arena or The Forum is a battle field located in Mount Olympus, more precisely at one of its edges and close to the Chamber of the Flame. This is probably the gods' favorite location to watch and even participate in battles, acting like a small coliseum. Two thrones, which are likely to belong to Zeus and Hera respectively, can be seem at the middle of its bleachers, but apparently Hercules is the Olympian who uses and commands the Arena more often, for his own entertainment.
Some details of the Arena: there is an iron gate under the mentioned thrones from which warriors and enemies can march in; there are big statues of goddesses on the walls and some walls have spiked vines overgrowing them.
The Forum of Hercules appeared in Ares' trailer for Ascension's Multiplayer and also in the Multiplayer beta. In Ascension, the players fight each other at night while Hercules stands on the middle of the bleachers, watching the warriors fighting below him.
This map is used for the Multiplayer mode Favour of the Gods, a free-for-all that supports four players in each match. Each player has to kill the other ones in order to gain the favor of the gods. The player that has more favour - that is, the one that has killed more enemy players - wins the match.
Hercules' role in the match is to occasionally jump down and cause shockwaves with his cestus that can damage the warriors and leave them open to combos, if they are not properly jumped. These shockwaves can also break the back walls of the arena and ring-out warriors whilst doing so.
Warriors can use the spiked walls that encompass the arena to damage their opponents: if someone is kicked into one of the said walls then they will be stuck there for a while.
A flurry of arrows can reign down from the sky if a warrior manages to get into the tunnel that serves as the entrance for the arena and light the brazier; anyone who is outside when the hail of arrows starts will be damaged severely. Normally, the said tunnel would have a large amount of spikes protruding out of the floor. These spikes sometimes sink back into the ground.
In the Trial of the Gods mode of the Arena, Hercules acts as the boss of the level, instead of simply creating shockwaves occasionally. The player(s) must defeat him in order to win the match.
In God of War IIIEdit
Kratos uses the walls that are overgrown with spiked vines to defeat Hercules, in order to retrieve the Nemean Cestus. After removing the Cestus from Hercules' hands, he continues to attack Kratos with his bare hands by grabbing, punching and throwing the statues around the Arena at him.
At a point of the fight, Hercules throws Kratos to the edge of the Arena, temporally stunning him, and lifts its whole ground, trying to make the Spartan slip and fall off, or simply making both him and the ground fall from the mountain. Kratos pulls himself back to the ground and jumps, pounding the floor down again before brutally smashing Hercules' face into the ground using the Cestus, with the last blow smashing the arena's floor to pieces.
Kratos and Hercules (now dead and gruesomely disfigured), tumble into the below sewers, where Kratos leaves his half-brother's body to rot. Before leaving, Kratos can take Hercules' Shoulder Guard on the bottom of the water.
Kratos' fight with Hercules clearly shows, and uses, several aspects of the arena.
