Bungie the developers of "Halo: Reach" has slammed 15,000 players for exploiting the game's credit system. According to a Bungie, "the developer has reset credit tallies for 15,000 players who have "egregiously" exploited a credit rip-off. The post reads, "Specifically, we targeted an exploit that allowed players to complete a Challenge 20+ times via itentional [sic] network manipulation (i.e., disconnects)"."
Bungie didn't specify any further details, but the instance spoken of highly resembles a credit hack that surfaced following the game's release last month. This cheat allowed players to rack up huge credit bonuses by manipulating the game via the means (see video below):
In addition to having their credit total nullified, players found to be cheating must sit through a one-day ban from amassing any additional credits.
