Found some tips stuff for the Jungle Inferno contracts.

- CTF Hellfire + Regen Powerup can be used for a variety of 'Take/Regen X Damage with X Class/Weapon' type objectives. You can also use the braziers on Egypt for these, but it's slower.
- For "Gain X amount of points in a life" contracts, take Engineer and keep your teleporters up and running around the clock. Keep a sentry near your teleporter to take out anyone near and for extra points.
- DeGroot Keep is a great map for quickly doing 'capture an objective X times' types of achievements, and is also the easiest 'alternative mode' map to finish.
- Black Box: The "Kill while explosive jumping" doesn't require you to use the Black Box, you can do it the Air Strike or via Market Gardening.
- Shotgun: Sentry Kills count as shotgun kills.
- Advanced/Expert Spy: Do not use the DR, it resets your "streak" aka the "Get 5 kills in a life" bonus.
- Degroot keep is the best for the crusader crossbow contract and amputator contract.
- Suijin is Sniper haven: if you're completing a contract for Sniper go there; however for Jarate it's easier to do it in a KOTH map where one area is crowded.
- "Defend the objective": You need to play a class that easily kills anyone under 1 second; a Sniper or a sticky trap does the job well. Mini-Sentries and stickies in props/ walls also work. Or go Spy/ Sniper.
- All of the defend CP contracts are easier if you sticky them then stand back somewhere safe. Don't try to push or damage the enemy team in any way until they're on the point. It sucks, but otherwise getting defends are pure luck.
- Medic Crusader Crosbow Contract: to get 6x long range shot and the 50 heals just do King Of The Hill, its ridiculously easy. For the 30x heal 200hp, find a sneaky spot where you can stay underwater. Just bob up when you are at ~60 HP and rinse and repeat.
