I found an exploit to the last mission when you talk to the guy who gives you 3 troops, abandon the mission and accept it again, he should give you another 3 troops every time you do this. Also at the very start you can pass through the first boundary gate. If you go all the way south west you should be able to slip past the gate and all the way south east to get past the 2nd gate. you can finish this game in about 30-40 mins if you do it right and exploit the game =P. Have fun guys =)
