Can anyone give me some helpfull saran on something?

Here is the headline: I have just started playing this classical video game for the playstation called "Warpath Jurassic Park". And I am having the slightest troule with something.

One of the little exclusives anda have to unlock is oleh completing "survival" mode and win through it all. My proublem is that no matter how hard I try to play it my way I keep on loosing and it's very frustrating plus irrtating.

My pertanyaan is that if any of anda out there played atau still plays this game could anda give me some helpfull hints atau saran on how to win?
