Just a tip for anyone else struggling with mission 23 (drop zone), who like me until now may not have realized all the parachute controls: In addition to the left and right arrow keys, you can also use UP and DOWN to help you control your descent. At first I thought the wind was weaker in my version of the game than in the video, but now I know I just wasn't using all the same controls that are possible in game.

You get a gold medal by finishing a campaign level on the FIRST TRY. If you know you're going to fail, just exit the game and go back in instead of accepting defeat.

Many of your guides provide no gold mission reward.

no puedo con la mision 7 e incluso lo he hecho en un solo turno y tambien ya lo hice como tu video pero nada solo obtengo plata

I just found out about Bazooka Skills 2 (I think?) in Basic Training, where you have to have the right angle and the right speed... basically luck.

All you need to do is fire the bazooka at full power about 5 degrees above the horizontal. It skims over the water!
Also works for Grenades.

Oh, and for #11 you can kill every Major with Firepunch if you're in the right spot.
I actually never used a single Skunk in that map :P

Wow.... You made #5 so hard for yourself. :P
You can put the Girder between the bush and the tran on the angle so you don't have to muddle with backflipping. You can leave half the worms as they are, as when you get the Jetpack utility you've enough jetpack fuel to get the crate and land safely.
#6, also, you can just constantly use the worm on the right. No need for rope tricks! (Well, I needed to get up that camel in the first place, but that's quite easy :P)

- You jump forwards by pressing ENTER once. Press two times quickly for a backwards jump.
- Jump upwards by pressing BACKSPACE once. Press two times quickly for a backflip jump.

This is an embarassing thing to ask but how do I jump?

thanks
