 The patch was exceptionally large; at the time it was normal to expect a game patch file to be up to 5 MB in size, whereas "SiN" first patch was over 31 MB.This was at a time when a substantial percentage of internet access was via dial-up, causing Activision to take the unusual step of offering to send CDs containing the patch to any owners of the game who did not have sufficient bandwidth to download it from the Internet.A likely explanation for the multitude of bugs is that the game may have been rushed to meet the 1998 Christmas season, possibly as an attempt to beat "Half-Life" to market.
