I have the game now....yeah, not quite how I expected it to be. There's still all the same gladiator action, however, you have to sneak around as this little pussy called Octavianus from time to time. It's terrible. He can't even attack guards from the front, and when he gets attacked, he goes down in one hit. Even if the guard butts him with his shield, he still gets knocked out. You have to sneak around like Metal Gear, and either smash them in the heads with pots, or strangle them with pieces of rope. As for new things:
Little people. You have to fight midgets that jump around ninja-style, and stab you with daggers.
As for weapons, you've got. . .
Giant rocks that you can throw, Spear, Apollo Spear, Power Maul, German Hand Axe, German Shield (When you're doing soldier stuff, you fight with german barbarians), Roma Shield, Spiked Shield, Dagger, Sling (it's like a sling shot, except it's industrial size and one-handed, when you pelt people with rocks it dizzies them), Oil Sling (this splashes them with oil), Torch (to set oiled people on fire), Barca's Ax (big germanic barbarian that you fight), Valcross Bow (special bow with flaming arrows), Roma Sai (it's one of those sai weapons, but longer), and the Morning Star (handle with a spiked ball connected by a chain). Those are all I've seen so far, aside from Octavianus's rope/pottery weapons. He's pathetic. the only time things become 'easier' for him, is when you steal a senate member/guard's uniform. However, you have to walk around, and you can't lean up against the wall, can't duck, can't run. Guards will also ask you questions because you look suspicious, and if you say the wrong things, 2 things can happen:
They can just kill you, or be very suspicious of you and try to watch you. However, when Agrippa becomes a gladiator, you partake in alot of gore.
