All the weapons

[momoneyinthebank]

I've beaten the game on SA, and im mission some of the weapons, mostly Sniper rifles that i couldn't get because of 1 enemy kill per mission.
Is there a way to replay the levels get all the weapons i missed and still keep my SA rating?

When you finish a game, a save is created that is titled "Completed Game". You can load that up, then quit to the main menu, select Start, select Current Game, and you will get a list of the missions. Pick one, and you get a weapons selection screen. You can now play through that mission bringing your choice of weapons along. Once that mission is completed, it will load in the next mission automatically, with the default weapon loadout again, but the weapons you just collected will be added to your total. You will always have to load in the most recent save in order to keep everything.

One thing I noticed was that my overall score improved after replaying some levels. It seems to track your best score in each level for the total.

how do you improve score if you beat all levels on SA?

Fewer shots, fewer kills, fewer close encounters, fewer saves if you are not playing on Professional.
