The game is great, but going bankrupt because of random accidents that demand huge payment is going to kill this game. i got bankrupt because of that, took a loan and then it happened again... i don´t want to start again.
ok guys i passed the game only by doing this: use only bazzoka man once they attack both air and ground, upgrade it to the max and upgrade the aids. forget about the other game units. produce them to insane amounts and you´ll pass the game.

Going bankrupt is only if you made wrong decisions when designing cars. If you do it right, there is no chance of random events.
