Perseus is a clothes shop with expensive suits and flashy clothes. There are two Perseus shops in Liberty City, both in Algonquin, but the clothes remains the same. No difference about it. One is in Middle Park East and the other is in The Exchange. There is no cash register and there is a guard who, if you have a weapon says to use it or put it away. The player can download a Perseus theme for their phone via Vipluxuryringtones.com. The player also gets a text message form Brucie soon after unlocking the second island telling him to "look VIP" and buy some clothes from Perseus.In certain missions,such as Mr and Mrs Bellic you have to wear clothing from Perseus.
