Marine Tactics:

You Can Snipe The Predators: Remember that the predators' gun sensors are on so they cannot snipe you. This also implies that you can snipe them in safety by keeping only your gun visible.
Choose A Plan:
    i)Stay Together: Easier to concentrate fire power but makes you a larger target.
    ii)Spread Out: Makes you a much less easy target but makes it more difficult to co-ordinate fire. Possibility of distract and hide tactics which have worked well before.
Fortify An Area: You'll find that having a clear defensive plan and roles increases your ability to survive.
Concentrate Your Fire Power: Use your numerical superiority by laying down concentrated fire at the predator. With a co-ordinated effort you should be able the keep the predators in their down time for much longer periods.
The Predators Don't Fear Dying: Predators might be easy to hit but they are invulnerable which means they may not behave as expected.
Communicate And Work Together: Whatever tactic you end up using post sentries to alert you to the predators' attack vectors.
Spread The Damage: This especially applies if you are fortifying a location; cycle those in more vulnerable spots who are low on lives with those who have more. Remember a marine lost is one less marine to defend with. It's far better to have all the marines on three lives than to have a few on ten and the rest dead.

Predator Tactics:

Do Not Play Conservatively: You will have to be aggressive to win, get up close and personal.
Don't Hide And Snipe: Your gun sensors are on, the Marines' are off. Enough said. Don't be a retard. :-)
Use Hit And Run Tactics:  Often camping right in the center of the marines will simply lead to your continually dying. However using a series of fast attacks you can take leech off a few lives each time and consistency pays off.
Co-operate With Your Team Mate(s): Co-ordinating your attacks spreads the fire and increases your chances of obtaining successful hits.
Go For Groups: Whenever possible target groups of two or more marines since this increases your chances of removing a life from the opposing team. If you get the opportunity to harass an individual marine, take it but don't become obsessed.
Take Out Annoying Marines: If there is a particular individual marine who is causing trouble concentrate your efforts on him first. Alternatively one predator can target him while the other continues the bombardment on the main group.
