A game named “Climber” recently surfaced over Steam and quickly vanished after scamming Dota 2 players with inventory worth of thousands. This scam was related to the much desired Dota 2 item ‘Dragonclaw Hook’, the item itself is worth more than $800 as we speak. Being a desirable item, anyone would want to trade it for his items.
