This is the final numbered version. The current Steam version is considered part of the 1.6 version family.
This version added "cheap" assault rifles such as the Galil and FAMAS; they were less expensive than the M4 and AK-47rifles.
The Counter-Terrorists had the option of giving up their main weapon to purchase a tactical shield. This item was often banned by servers, since a CT with the shield in crouch position is impervious to firepower, and certain mods would allow players to use an assault rifle or submachine gun with the shield. AWP delay was also added.
