another thing to note is that keller get stronger everytime u enter to its hyperspace and it get stronger if u take too much time to finish the game keller in year 30 is way more harder than keller in year 1 most likely u can easily kill keller in year 1 with 2 missile but in year 30 u need 5 torpedo, vertix and fly in edge and just hold ctrl it take 1 hour for me to finish him (dominator difficulty was on 150% but i dont think it matter that much for 200% difficulty it just take more time) and as random50 says use droid junior it make huge difference and forget about health pack in the middle its a trap
