Command & Conquer: Tiberian Sun Cheats

Fill up your harvester with as much blue tiberian as it can hold. Then, with a group of Light Infantry, park your Harvester by any of the enemy's buildings. The building, your harvester, and surrounding units and buildings will explode, causing your enemy to be forced to rebuild again!

Edit sun.ini in the game directory and you can push the screen resolution way up from the pathetic 640x480 standard

Look for...

[Video]
ScreenWidth=640
ScreenHeight=480
StretchMovies=no

And just change the values to something more suiting to your PC + Monitor (as Tib Sun looks stupid at 640x480 on bigger monitors)

On my machine I run the game at 1280x1024 with no problems, stops so much scrolling around and you can see all the build options too!

This works for GDI only. You must have access to an Orca Carryall and a Mobile Sensor Array. Take the Carryall, force it to load on the MSA and fly it into suspected Nod Base Territory which is cloaked. The MSA will uncover all the buildings on the minimap, and if it is attacked, the surrounding buildings near the attacker will also be revealed! Cool, huh?

This part works for Nod. Take the MSA and drive it straight into the enemy base which is cloaked. It has the same effect.
