I'm sure many of us have had trouble with getting good scores and unlocking the necessary achievements that are only accomplished in Survival Mode.

Well I think I have come up with a great strategy that is sure to work for everyone, if these steps are followed right that is!

However, for this to work, you'll need the Ranger Reinforcement upgrade you can only unlock by purchasing it from Survival Mode's Vending Machine.

First of all, you'll need to set up your HQ and a Power Station behind it as far to the right as possible, seen here:



Next, you'll need to fit in as many Supply Stations as possible here:



After wards, you'll need to get as many Rangers in your army as possible (I was able to get 22 when I did this)

The Hybrids coming from the left will stop advancing around halfway across the field, seen here:



I wouldn't recommend engaging these guys at all. And oddly enough, they won't steel your resource point either...

All you'll have to do is stay within the recharge range of your HQ so you can constantly keep a shield up and heal your Rangers. Then you just shoot like crazy at the Hybrids that come in towards your right, making sure you heal your Rangers as they are hurt, and replacing them as they die off.

I think that's about it! If there's anything that I need to explain, or you guys have suggestions to make this even better, just say!
