Modern gamers are soft. Back on the ZX Spectrum the concept of saving did not exist, you had to complete Jet Set Willy in one go - man up! Modern gamers expect a save point every few seconds just in case they die, boohoo. Pid is a local 2 player co-op game that was hard to begin with, but even harder when the save files did not always work on the 360. Now that is too tough, so a patch has arrived.
