Gm... Don't press enter after you put in a cheat. Just head back to the menu. P.S: Only cheat I know/remember is 'QUICK', which cuts time down to 30 seconds...
Undead, Trolls, and Demons are the three best factions. Night Elves, Human Alliance, and Orcs of the North are some other good ones, if you use them right...
When fighting the unknown creatures, I just line up my samurai and keep them on "will" and slide it forward, using the freezing thing to hold the enemies back. After they cross to the other edge of the screen, they kill the long ranged enemies and the melee ones just get slaughtered. I usually lose a handfull of samurai though.
I don't think this is the full version. I played earlier, and you could only buy resources, not sell. I think ttback is slowly building up to the full version, which may include the skirmish mode I suggested...
1) Pick Virus. 2)Start in Canada, New Zealand, Cuba, Greenland, or Madagascar.If you do not get there restart. 3)Sell starting symptoms, if any, and buy sneezing. 4)Buy 1-1-1-0 resistances but no transmissions (they trigger closures). 5) Once three countries are infected, sell sneezing to get rid of visibility. 6)Wait until all countries are infected. If Madagascar closes its shipyards or is not infected in 30 days, restart. 7)Buy all four drug resistances, sneezing, coughing, and vomiting. 8)After a few days, unlock tiers 2-3, keeping whatever symptoms it gives you. 9)Buy fever, fatigue, diarrhea, pulmonary edema, and hypersensitivity. 10) Wait until everyone dies.
