Sabre Squadron introduced nine new single player missions, seven new multi-player maps, and a now finished, death-match map called "Poland", which had been featured in the game's intro and was titled "London" and available for play in its unfinished state before this release, new weapons: the RPzB 54, the MAS-36, the G43, a suppressed P08 and a Harrington & Richardson Mk VI flare pistol; the ability to hold your breath while looking through a telescopic sight, a co-operative multi-player mode, along with access to the original Hidden and Dangerous 2 missions through Sabre Squadron's interface.
