Boso, your mission, should you choose to accept it is to survive till the 28th of January on little or nothing. To aid you, you have to use a weapon called 'budgeting' to it's maximum capabilities. Your cooking skills will also come in handy, as you will have to create weapons called 'packed lunches' on a regular basis.
Some of your enemies that will try and attack you before then are 'Starbucks', 'KFC', 'Subway', you can succumb to them once in a while, but try and get your friends to 'give you cover', when you go in. But be warned, you have 2 credit card bills coming soon, that will test your resolve to the max. You also have 2 phone bills coming, which will also attempt to destroy you.
All the best soldier. See you on the other side.
