I'm stuck on the red square mission. I have the methanol injection already, but I don't have the proximity fuze. I have 2000 points saved up but the fuze costs 4000.

Is there any way I can either go back and earn prestige from previous missions (tried this, didn't appear to work) or get prestige points another way (multiplayer?)

I don't want to start all over again if I can help it, and from what I've read I really need the proximity fuze (and a lot of luck) to get past this mission.

Thanks for any help

of curse u can, but you need to earn more prestige than in your best flight (like 2000, you have to earn 3000 to get 1000), destroy all oramge enemys and theres an upgrade that allows you to earn even more prestige in missions, I dont like cheats but you can also use a cheat to earn 2000 prestige points straight but if you use a cheat 3 times in a mission the mission will end automaticaly. Hope this help you.

awesome, thanks!
