Accidentally discovered a modified version of Antbuster; if I were to describe it with two words, nothing fits better than "crazy". If I must add another word, I would use "very". In the modified version, weapons are upgraded by one level and the initial amount of money is virtually countless, which takes away all the challenges in the game. However, if you have been frustrated with the original version for a long time like me, you can use this crazy version to let off some steam, which feels pretty good.
