Play Chapter 2: Ruins Of Crystal City - The Lost Vault, and proceed through the mission until you get the "Search for the leaders of the Insecticons" objective. Before you can fight the leaders, there will be three swarms of Insecticons you have to kill. Switch to Starscream, and clear out the waves of Insecticon enemies. After defeating the three swarms, walk over to the terminal and press X. Then, press B to back out of the terminal. This will save your progress. Pause the game, and select the "Restart From Last Checkpoint" option to start at the beginning of the swarm attacks again. Repeat this process as many times as desired. Note: You will also be completing challenges that give you Gear Boxes that contain x4, x5, and x6 XP multipliers to make the process faster. Additionally, equip any hack that will give you extra XP.
Play Chapter 7, and proceed through the mission until reaching the end. Hack the weapons terminal before entering the final turret section. Select "No Shield Regen" while hacking to get +300% experience points. Also, slot the x6 XP multiplier multiple times, if possible. Go to the Jazz prison area, and clear out the basic enemies. Once you are down below, go to the objective marker, and jump on the turret. After the enemies spawn, use the T.E.C.H. XP bonuses, and destroy each incoming enemy. Use each bonus as the previous one lifts. Then, either wait for Jazz to die or pause the game, and select the "Restart From Last Checkpoint" option before the end of this section to continue farming experience points. You will retain the previously earned experience points after restarting and can repeat the process as many times as desired.
Add one of the following hacks at a loadout terminal to get the corresponding bonus:
Exploding Enemies: Gives a 75 percent XP boost, and every time an enemy dies, they explode harming everything around them. It is recommended if you primarily use ranged attacks.
More Ammo: Enemies drop more ammunition, you have less health, and gain a 75 percent XP boost. It is recommended if you can frequently take cover.
More Health: Gives a 125 percent XP boost, and enemies drop more health than ammo. It is recommended if your weapon has decent ammunition capacity.
No Shield Regen: Gives a 300 percent XP boost, but your shield does not regenerate unless you defeat an enemy. It is recommended if you can aim well and take cover frequently.
Tough Guys: Gives a 200 percent XP boost, but enemies inflict more damage and have less health. It is recommended if you can avoid damage or take cover until your shield regenerates.
The following T.E.C.H. assists are recommended for the indicated situations:
Battle Drone with Cybertronian Ultimate Repair Energy Drone: The Battle Drone will steadily attack enemies within range, which is useful when you need cover fire or need to know where enemies are located. C.U.R.E.D. will heal a nearby ally. You can only have one of the drones active at a time.
Diffraction Barrier: Since the barrier does not move, it does not protect you from moving enemies. It is most useful when you need to replenish your shield without cover.
Energon Heal Burst: It is useful when in a support role. It immediately heals allies and also allows them to heal over time.
Energon Recharger with Shield Restore Booster: This combination allows you to regenerate health very quickly while having the ability to immediately restore your shield as soon as the Energon Recharger effect wears off.
Guided Cluster Grenades: It places heat-seeking mines that are effective when used near a group of enemies.
Vehicle Booster: It gives better armor and increases your damage while in vehicle mode. It is more beneficial for aerial vehicles.
The following weapons are recommended for the indicated situations:
Melee: It is the best way to attack at close range.
Nucleon Charge Rifle: It is the best sniper rifle, but it requires time to charge once you look through the scope. It is best used when in a safe position at far range.
Riot Cannon: It has a wide blast radius and does a large amount of damage. However, it has limited ammunition capacity, but it can be upgraded.
Thermo Rocket Cannon: It is a heavy weapon that quickly locks-on to an enemy with a guided missile. It rarely misses but has very limited ammunition.
V32.CYBR Corrupt@r: It turns an enemy to your side temporarily. They will then immediately attack the closest enemy, but it is not as effective as you can be. It is best used when you are outnumbered.
X18 Scrapmaker: It does not require reloads, but it has a small amount of cooldown before it can be fired.
