Well for one thing, it's not actually a Viper game. Sogna made it, but Viper isn't in the title.
A guide isn't really neccessary. It's painfully linear. You just have to go to all the right rooms during the introduction phase, which just takes too long because of the boring "walking through the halls" transition scene. Once you get to the attack of the clones, I think you can just sit back and hold down the spacebar.
