I didn't realise at first that the Triple Threat, which ordinarily launches three bombs at a time in a horizontal line, can launch three in a vertical line if you hold the aim button. I found it a great weapon once I'd cottoned it was more versatile than I'd initially realised.
I love the Electric Smoke titan power. It's good for the occasional pilot kill. It's better for getting people to jump off your titan (whilst dashing backwards and shooting them). But it's great when fighting other titans - and they don't really mention that in the tutorial.
Causes lots of damage to titans, but also allows you to dash away from them (preferably diagonally backwards) so you can reload and open up on them while they're blinded, and hopefully your shields recharge before they figure out where you are, but theirs are still damaged thanks to a combination of the smoke and any ordinance you're sent their way while you're backing away.
Haven't tried using cluster missiles to remove pilots - though I did see it as a loading screen tip.
So you stand next to a wall, fire your secondary weapon, and do a quick 180 so the explosions are at your back?

Top Gun (G2A4) Tiers: 5, 15, 30, 50, 75
If It Moves... (XO-16) Tiers: 10, 25, 50, 100, 200

The chaingun challenges should be easy enough. Melee 25 with Strider might be a slight problem.. I don't have much experience with the G2A4.
Remember to keep Burn Cards for CAR SMG and Archer HR.
Generation 8
EXP Modifier: x 2.5
Requirements to Next Level:
All I Do Is Win (General) Tiers: 10, 30, 50, 70, 100
Look Out Below! (Kills) Tiers: 1, 5, 15, 30, 50
Executioner (Melee Kills) Tiers: 1, 5, 10, 15, 25
Critically Conditioned 40mm Cannon (Titan Weapons) Tiers: 5, 15, 30, 50, 75
If It Moves... (C.A.R. SMG) Tiers: 10, 25, 50, 100, 200
Top Gun (C.A.R. SMG) Tiers: 5, 15, 30, 50, 75
Titan Killer (Archer Heavy Rocket) Tiers: 1, 3, 5, 7, 10
That 2.5 xp modifier is almost completely useless. You'll be at level fifty way before you get close to a hundred wins, fifty titanfall crushes, or 25 Executioner moves. CAR should be easy enough, as should the Archer. I've not used the 40mm cannon much but 75 critical hits sounds perfectly doable. (The only good thing about the xp modifier is you'll unlock the weapons you need a little bit faster.)
Remember to keep Burn Cards for Cloak, Nuclear Ejection, Smart Pistol, Hemlock, and Kraber. The next regeneration is going to be a long haul...
