Ok, If you are not good at this game and think its hard to get a high score, then that will change by the end of this guide, that is, if you do everything exactly as I say.
Very Good Tips (do these or you will not do well)!!
– On each level, try to get at least a 20×3 bonus. On the first level though, it may only be possible to get an 18×3, but that’s all right. This is where pretty much all of your points will come from.
– For the first few levels, buy only guns, nothing else!
– When you get an option to buy a radar, BUY IT!
