You choose when to invade, and can only be invaded under certain conditions. If it's the same as Demon's Souls, you can only be invaded (or summon help) when in 'body' form, and you're only in that form after you kill a boss. The first time you die, you'll be back to 'soul' form. You'll be spending the majority of the game like this, where your game cannot be affected by others, but you can ask to be summoned into other players' games to help them with their quest. Not only is this brilliant fun, but a great way to level up.|
If you REALLY don't want to get invaded, just suicide every time you're in body form!
