Burning and freezing your enemies
To burn and freeze your enemies at the same time buy the second wrench upgrade and get 65 skill points to unlock the Super Morphing freeze wrench cheat. Turn it on and then when you hit an enemy with your wrench they burn on the outside, but freeze on the inside and shatter into little pieces when they die.
Complete Endzone Easily
To easily complete the Endzone dread challenge equip the shock mod to the Dual Vipers or Dual Rapters. Stand at where your enemies appear and shoot once or twice and the hole line of enemies will die.
Easy Arbiter XP
Equip the shock mod and the XP mod to the Arbiter and do the first two rounds of Swarmer Suprise. After you do the first two rounds jump in the lava and do it again.
Once you have the Dual Vipers upgraded to Dual Raptors, equip Jackpot mod (two if you have them) and Shock mod. Go to the Endzone Challenge in the Battledome. Use the Raptors repeatedly. This is a good place to train any weapon.
If you are doing the challenge with Dual Raptors, you should get a large amount of bolts quickly (about 6 million per play).
Use the Magma or Vulcan Cannon and equip the Jackpot mods (as many as possible). Do the Endzone Challenge. Stand a good but close distance from the starting line and repeatedly fire. It is possible to get close to 3 million bolts.
Easy weapon experience
In Endzone challenge, on challenge mode, equip Exp mods on any Mega weapon and it will grow at a very fast rate. You may need to repeat this a few times, but it is worth it.
