At BioTech Labs, go into Dr. Zwiberg's office and insert the 3 serpent keys. Then go down the stiars and to the left is a box filled with free, unlimited ammunition!
When I got here it took me a few tries to kill him. First grab the medi-kit. Push triangle to push up against the wall. Then just move left shoot him and then go to the right. If you are lucky you can meet him just as he's coming around the corner. When I did I was able to sit and shoot at him while he always missed. (Hint: If you are fast at pushing against the wall he will stay as far back as possable.
By the time yo get here you should have at least 3 proksimity mines place them in the middlie of the walking area one on both ends and on mid way (between the contaniers ) if your luky he wil hit all the mines and fall over dead.
The first battle with Ramerez if VERY HARD. When you battle Ramirez's spiders, shoot them once then stand over them. Press Action, then guide the spiders towards the door. Press Action again to make the spiders jump at the door. Eventually they will melt the mechanism with their acid blood and you can enter. To defeat Ramirez the second time, get out the machine gun and just shoot away. You have to shoot the lights first, and watch yor health.
You can only use the handgun. There are five circular plates on the floor. Stand on one and a lighting bolt will hit it. It can cause damage to you. However, if timed correctly, you can lure Gladiator towards you and jump out of the way, allowing the bolt to hit him instead. The only way to kill him is to use the plates.
On the map it looks like the bomb is directly the bridge...Well it is of curse but it's not that easy. Press select or start"I don't remember" look at the map and go to the far view. You have to go the HOLE WAY AROUND the dam. Once you get in the sewer. Be careful becuase they WILL trick you if you are not ready for it.
To score higher points when playing LEILA missions, find everything that you possibly can and do not use your grenades until you get to Ramirez and his Spiders. This will aid in later missions.
To beat Ramirez on the ship Queen of hearts, you need to run behind the box in the middle and push the triangle button to back up to the box, get youre grenades out and go to the side of the box push the R1 button to pop out to the side and throw a grenade at the lights, it will blow up the lights. Ounce you have blown out all the lights on thats side. Scoot to the other side of the box and do the same thing to the lights on that side. When all of the lights are blown up he will no longer have his machine gun so you can go out into the open. ramirez will now throw grenades at you so you need to run to one side of the helepad, when he gets ready to throw a grenade run to the others side to miss it, he will throw three grenades then he will pause for a couple seconds, this is you need to shoot him, I can usually get two shots on him with the shotgun, if you use the regular gun you can probably get more on him. After that he will start throwing grenades again so you need to do the same thing you did earlier to evoid the grenades,after three grenades he will pause, so pump him full of lead. Continue to do this till he is dead.
