******Side NOTE****** If you are using official game guide maps, they are missing cubes******Look below for locations to those. **See bottom of solution for original game guide maps**
--Autobot Chapter 1 --Only missing 1 from map, #100 is located about 30 yards NorthWest of the Hunt Sub-mission. Just left of the road.
--Autobot Chapter 2 --This map is actually complete, all 100 shown.
--Autobot Chapter 3 --This map is missing 2. #99 is located due East from where you start (NorthEast of map) at the end of the tunnel in front of fan. #100 is located to the west of Secret Icon 2 (look to the left of the icon on map at the close pair of cubes, there's actually 3 there, its the last one you need)
--Autobot Chapter 4 --This map is missing 6. #95,96,97 and 98 is located south of secret icon 4. (cross street south from icon and all 4 are on those rooftops) #99 is just east of the previous 4 on the grass right before water. #100 is located to the west of the previous 4 just NE of Scavenger sub-mission.
--Decepticon Chapter 1--This map is missing 2. #99 is located just west of the destruction sub-mission. #100 is in the main base east a ways from the "Start" (first mission). look at map to see the cube east of the green start icon and the last cube is just NE from that within sight
--Decepticon Chapter 2--This map is missing 1 AND has 1 EXTRA cube shown on map that doesn't exist. #100 is located on the highway right where secret icon 2 is shown. The one they have shown that isn't there is located in the far south, middle highway ramps. (See the cluster of 6 cubes at those on and off ramps? There's really only 5 there so don't waste your time running in circles like i did)
--Decepticon Chapter 3--This map is missing 2. #99 is located directly north of the Sumo sub-mission. #100 is located a short distance west of secret icon 2.
--Decepticon Chapter 4--This map is missing 7. #94, 95 and 96 are located in the far SouthWest of map in the construction yard on ground level. #97 is located directly south of secret icon 5. #98 is located NorthEast of Sumo sub-mission. (Just follow grass north from sub-mission, cant miss it) #99 is dead center of the grassy park (center of map) in middle of trees/shrubs on a hill. #100 is harder to describe but if you draw a line due north from #99 you will run into it near the top of map. (looking at top right corner of map at the single cube, move SouthWest to the next cube shown. Run straight south down that road until you run into the buildings in front of you, the cube is right there at building wall or on the rooftop.

You now have attained all 800 cubes no thanks to the makers of the guide that was one of the most incomplete I have ever seen. Hopefully you didn't buy it or the assassin's creed one or you got cheated bad lol.
Gratz on the achievement everyone! Hope this helps all of you who followed the maps and still missed a few.

This is a video I made that uncovers a hidden cube on the Soccent Military base. Hope this was help to you because I was looking for this for hours.

This achievement can be annoying and time consuming. You must collect all 800 cubes spread throughout the game, find all secret icons, get all skill marks, complete all the
sub-missions and play through all missions including
sub-missions. Don't forget to play the Cybertron levels also.

After you have done the above listed items, you must then replay any chapter to unlock the achievement.

To add on to what Embracing said in his post:

If anyone is thinking about going for this achievement, the best thing that I can advise is that you do not leave the level until you have all of the cubes collected as well as the Autobot/Decepticon icons.

In addition, it helped me out immensely if you print out the maps of each of the levels where the cubes are located and then cross them off as you collect them. However, when you are looking at the maps, the START point is where the first mission is located, (this messed me up a few times).

Also, another tactic that I did was to do a spiral pattern when collecting the cubes. Start from the outside of the map and work your way in, that way if you miss any they are located in easy to see places instead of middle of nowhere.

Hope this helps, please leave me feedback or PM me if you have questions.
