I was hanging around, ticking off nexos when i found some combos that are useful for defeating them (You must have all the weapons described and temporal fist)

SuperBounce
1. PK a Nexos
2. Hold them to the ground (Place them on the ground without letting go)
3. Switch to your Superballer
4. Stop Time
5. use your jetpack to carry them up as high as your jetpack can go
6. Aim down Quick!
7. Use temporal fist and start time again.
8. Watch the Nexos bounce extremely high, possibly disappearing into the sky

KamiKaze (Works effectively against everything except Helis)

1. Pk something
2. Unload all the dislocators on them (Shoot the dislocator at the target)
3. Stop Time
4. Shoot an ion detonator so it will stick to the target (Do NOT detonate it)
5. Use temporal fist (On Somebody you want to kill)
6. Start time
7. Detonate whenever you like :)

A Free Ride (Not actually a combo)
1. stand on a car
2. shoot all the dislocators at the car
3. let it fly a bit
4. Shoot superballs at it
5. now you can see a great view of the invasion site!
