[hit&run2]

hello, i just started playing about a week ago. a friend told me that all the best players come here and they could teach me. i use strider and doom, but i cant find a good third character. also i need some strategies. could anyone help?

[hadoken king]

sentinel
commando
magneto

and btw, strider / doom isn't the best team to start with

best teams to start wtih

storm/sentinel/commando
sentinel/cable/commando
