Command & Conquer: Renegade Cheats

Endless time in Skirmish mode
If You are getting tired of getting only 25 minutes of playtime in the skirmish mode (multiplay practice) Simply open the "svrcfg_skirmish.ini" file under \westwood\Renegade\Data directory. Not only can you change gametime (0 = endless), but you can also change the amount of money you start with..

Buggy Rush from Berserker
Since the Nod Buggies are only 300 credits, a couple guys can buy some and take a passenger with them. The most effictive combinations would be 2 Engineers, A Technician and an Engineer, 2 Technicians, or a Technician and someone to cover them. Since GDI's Advanced Gaurd Tower doesn't destroy the Buggies extremely fast they can usually get to a building and drop off their passengers to make short work of any building.

More multiplayer units
Press F8 and enter extras fnkqrrm. In the Purchase terminal, hold down ALT when you click on Vehicles or Characters to access the extras.

Dealing With Mutants
When you come up against those tiberium mutated monsters, use either a laser-based weapon or the flame thrower - shooting them with tiberium guns like the chem sprayer only heals them.

Better Hum-Vees and Dune Buggies
To augment the destructive ability of any vehicle, try becoming a Technician or Hotwire and rig your ride with proximity mines!

Burning Chem-Warriors
NOD Chem-Warriors are highly vulnerable to fire. Flame on! Too bad the GDI can't get flamethrowers in multiplay

Change Map List
You can also put a maplist into the svrcfg_skirmish.ini, but it will still play the original map first. Here's an example of what the map list will look like:

MapName00=C&C_Canyon.mix
MapName01=C&C_Hourglass.mix
MapName02=C&C_Mesa.mix
MapName03=C&C_Volcano.mix

Then, after you finish the first round on C&C_Under, it will load Canyon. There will be no AI on the other maps, but at least you can run around, explore, and get an idea for rush tactics. You can see all the multimaps in the appropriate directory, just have the .mix filename as the map name. If you need a template, just make a dedicated (or non-dedicated, I suppose) server configuration and save the config. It will be an INI file that you named for it when you saved it. It will look exactly the same, and you can see how it manages the maplist and other variables.
