i know a multiplayer option is feasible but how about this
some secret or bonus level ( like Miah` s PC)
that require multiple users to brute force a server in tandem
DDoS or eliptic curve cypher
goal would be to get the file ( ie fake onlink 2 source code) or kill miah` s computer (again ?!?, ok sorry that aint funny
)as fast as possible
top ranked agents would be shown in game in the agent ranking list or online orso
