1. The beginning will be hard because you do not have very good genomes yet. Keep trying and don't get frustrated, when you get to the good genomes everything will be good. 2. The best trait to invest in is Reproduction. Quantity will always trump quality. 3. After, go for Strength and Defense. Defense will help you survive (something you lack greatly in the beginning) and strength will help you capture cells more easily. 4. Agility is worth nothing; it only measures how fast your viruses turn. Speed is nominally useful, but still inferior to fast reproduction. 5. Cancerous cells are the best special cells, followed by bacteria, then red blood, then white blood. Of course, by now you should be making orders in split seconds so as to get them all at approximately the same time. 6. The AI is ruthless, but their main weakness is overpressing the attack, meaning to say that they keep attacking to the point where their defenses are extremely weak. Attack them as soon as this happens. 7. The beginning is the most important stage of the game; it's very hard to get back up if you don't get a lead. You usually start with 100 viruses in one cell, so it's generally best to deploy into two different cells in the first few seconds of the game. 8. The best defense is a good offense. If you can subdue your enemy's cells before they can attack, they will be unable to score major victories. 9. You can't have negative traits (negative speed, agility, etc.), so if you don't have anything there, then don't worry about it. The key to winning is specialization; a well-rounded virus will not do well. 10. Don't be afraid to press X and terminate the experiment. It happens.
My total stats were: 0 Speed, 10 Strength, 0 Agility, 11 Defense (max), 11 Reproduction (max). Although my viruses were very slow, the sheer number of them I could produce in a short time combined with their powerful strength allowed me to steamroller through the opposing viruses. The defense helped protect the cells I had already captured, preventing them from falling back into enemy hands.
Just get as many cells as fast as possible, but make sure your cells have 30+ before you send out the infectors. This gives you the best percentage of survival. Try to keep all your stats, like reproduction, speed, strength (etc.) at the same level. So If strength is 4, all the rest should be at most 6, at least 3. This will give your infectors a round about tactic.
it took a little while to get going but once you do its a pretty fun game. i tried to get my reproduction up as high as i could without sacrificing other attributes and that worked pretty well
Beat the game in under 10 minutes. Took less than 10 sec to beat most rounds. Speed and Strengh make you invincible. Just quickly take over every free cell when the game starts and start jumping in on the evemy the sec every cell is taken. Waiting for the Live game servers to start up again 7:3 before the 2nd crash.
