in the 1st part you will start off on and open grounds , on you left n right got ramp ( you can take cover here ) which will lead u up to the upper level / platform , now, what you need to do is to overheat trypticon's shoulder missile, how to do that ?

- go up following the ramp and activate a switch upstairs ( might need to wait a while for it to appear )
- once activated, quickly run down to the left side ramp and take cover
- look up on the right side u should see the moving batteries/power cells, shoot the one that moves towards the enemy to overload his shoulder missile pod.
- after few battery exploded the shoulder missile pod should be destroyed,  move back up the platform to activate another switch.
- quickly run n take cover on the right side ramp.
- repeat the battery/power cells shooting procedure.
- trypticon will be angry now and use his tail attack, how to evade ?
- notice that before he attacks , u can see debris / dirt will rise from the ground around u , if u near that area quickly transform n run away to another area where there is debris / dirt rising, u should be safe here.
- after the tail attack, you can shoot the glowing 2 red part somewhere below his chests. (need few rounds if playing hard to destroy 1 part)
- successfully destroy the 2 parts , there will be a cut scene n u will enter the 2nd part of the chapter.

take note that you will be taken to a ground exactly the same like the 1st part, but dont be fooled, you cant take cover anywhere in this ground, but dont panicked, there is a way to defeat him without taking cover

you should start of the lower ground , not the platform
- run to the left side (near the ramp) and grab the x12 scrapmaker + ammo .

let me explains the enemy's attack pattern on this 2nd part, he will have 4 types of attacks, USUALLY he will start of with his gay homing missiles attacks , then something like homing fireballs attacks then the tail attack (quite same like the 1st part, only this time there will be spiders spawned after the attack) and last the not so gay missile attack (shortly after the tail + spider spawned, but not so deadly + can ignore).
 
- once u have the 2 items, quickly transform and drive in circle (big circle + pressing L1) . no need to go up the ramp (tried this b4 and always stuck n died)   
- just drive in big circle on the the lower ground and you should be safe from his missiles + fireballs + tail attacks, once u successfully evade all those attacks , ignore the spiders and you should be able to attack him (first spot is behind his head something like a panel, destroy that then u can attack the left n right side) 
- usually u cant destroy the thing in 1 round, so to be safe hit it will 1 round of ammo, then transform to vehicle form n rammed the spiders , remember to take ammo also in this process.
- just repeat to drive in big circle and fire at the enemy after his tail attack.
- upon destroying the last enemy's spot / vent / whatever , move closer to him in the middle a bit to get smashed and get a trophy
