Not sure how hard it would be but maybe you could make a "contract tree" to choose what contracts we could complete for the day. You could balance out the rewards and such with each tree while giving players the option to continue in contracts
This game is has a lot of fun physics going on. No wonder it's rated one of the top eight games for young engineers :) http://www.wired.com/gamelife/2012/12/videogames-engineering-kids/?pid=3191&viewall=true
Level 8: Couldn't find a way not the waste the medkit without dying :/ Sorry
Level 9: Grab the sniper bullet, go through the sewers, put the other 2 guys in surround zone, snipe the barrel above the lowest one, open gate, let surround damage do the rest.
Level 10: Grab the smoke and sniper, smoke the first guy and back stab him after it wears, go to the top room, snipe the SECOND guy by aligning yourself a little lower than the 1st one and snipe, use the previously trapped soldier to backstab the 1st, free the 3rd soldier, get to the top of the building, line up 2 guys next to the 2nd room entrance on opposite sides, snipe a terrorist in the 2nd building, let surround damage do the rest.
Hoped this helped and please reply if you found a solution or a better one :D
Level 6: Detour the whole map by going right and wall hugging. Kill door guard in the back, hold fire, kill the guy by the plane. Unfortunately, I couldn't find a way to get the guys in the building.
Level 7:Smoke the upper guy, kill the uppermost guy, hold fire, kill the lowest guy outside, take the smoke and smoke only ONE of the two in the building and kill the other, kill the other after smoke wears, and backstab the last guy.
ACHIEVEMENT GUIDE! (Part 1 Incomplete)
Level 1:Take a detour around the 3 warehouses
Level 2: Hug the wall with the 2 blue boxes
Level 3: Hold fire, kill first guy, hold fire, hug the left wall and go past the 2nd guy, kill the 3rd, hold fire, hug the same corner, kill the 2nd guy
Level 4: Got this by luck but, flash the first guy and just charge the 2nd
Level 5: Get the smoke and smoke ONE of the 2 in the building and kill the non-smoked one from the back by going past the smoked one. Hold fire and kill the guy you smoked after it wears off. Grab the frag and get 2 parts to hit the last guy.
LOL
This will DESTROY all progress you have made so far, are we clear?!
Are you REALLY sure you want to delete your progress?
You confirm that you WON'T sue us after deleting your own progress?
At first I thought about the game...simple task...scare people out of the house using numerous objects...then I learned you can scare the crap out of people so that they will commit suicide :)
