Actually it's a clone of the tower defense level in warcraft. The game you referred to is still in beta, and is itself a clone of either this game or warcraft.
I can beat levels 1-5 with just machine guns. Level 6 could probably be beaten with just machine guns, but you'd need a better maze than I've come up with.
Random101:
I tried it an beat the first 3 levels with just machine guns. I didn't try the rest yet. My scores were much higher just using machine guns.
the invisible tower bug has happened to me 3 times. all three times I sold a tower, placed a different type of tower in the same spot, upgraded it fully, then it went invis.
It looks like the bug where it calculates the percentage killed wrong only happens when you unlock a level. so the first time you beat a level it seems like it doesn't count the creeps after the boss on the last wave.
The "Last Caress" virus wiped out the world this way:
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 (unless it is what you started with, just keep it). 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. keep this comment alive.
