at outer base says:
There are new secrets,ammo and weapons.ask other players to give you a boost.
I want to ask other players for secrets . i know a secret:


outer base:

go in front then kill enemies, take it right where you get out and kill enemies and then go to the boxes and look at the window from here, and above the window is a super shotgun.

Here is the other cool secret! In the second level, at the end of the level where you are supposed to drop down into the sewers. There is that floor which opens up so that you can jump into a hole. Instead, before you hit the button, make a human tower there of probably 3 players, and you can reach a Chaingun.

note:I copied this from another topic, to be more secrets on this topic



THIS IS NOT A SECRET

I hope this is a secret, I'm not sure because I need teammates to try:

this secret is in base3 (level 3):

after you take the blue key go to the door where the key is required, some flyers come somewhere, and from where flyers come, I think there is secret

Sorry to be a bummer, but I think the only extra ammo/weapons are in the first level. And at the beggining of the 4th unit (extra bullets, and the tank drops a grenade launcher, but that's because there's a crapload of monsters at the beggining of that unit)

It would be nice to have more ammo, I don't see that happening though. So the only ways I can see people using ammo efficiently, is if only one person uses the ammo, and everyone else just carries extra ammo (at that point it's not really co-op, but more like using other characters as storages). Or to go to a very easy to get ammo location, then the host presses O to return to start map with the ammo you just got.... However, I haven't found anyone that's patient enough to do that, cause it takes a while, and there's no action.

LoL.... There is always action..
And, a secret, on the lava unit (the unit where is a lot of lava), somwhere, there is, inside lava, a quad an some fun stuff... I've only seen it (thanks to pain..)

Anywa, it would be fun to place more secrets, as long as more monsters to make it harder.

maybe on unit 9, lower palace (unit 9 level 2 OR 9/2) there, you have to jump a while in lava then you will see a secret place with quad damage and some healths; but how did you die so fast ? maybe you've had low health and no armor and no cells for power shield (i know, this post is really old )
