I started to play this game 2 days ago. I'm a total noob on this one and didn't play the N64 version.
I'm on Mission 4 (I think) "A51 Infiltration" where you have to destroy the antenna that can go up and down. As far as I have seen on YT, you have to destroy it with the "explosives" weapon. The problem here is that when I select that weapon, it shows nothing on the screen! So, I can't do anything now.
Is this a glitch? Do I have to do something else?
