I've never actually gone online but i've heard you must connect it via an ethernet cable which plugs into the front of the PS2. If its a PS2 slim then it should have Online built into it.





If you want a good online game then try Killzone - very nice game - I played it at a friends house once and loved it - so i went and bought it. Its fun online and offline - if you make a match online in this game go with the level beachead - wicked for multiplayer
you cant only on a xbox, xbox 360 and PS3
you cant!
