General tips for surviving in the jungle
As the game starts, you are ambushed by soldiers cunningly concealed behind trees. Study their positions and the, whilst keeping you distance, pick them off one by one. When you come to the steep hill with the gun tower situated at the bottom, grab the rocket launcher from behind one of the trees and destroy the tower from a distance. The rest of the level should be plain sailing thanks to your trusty rocket launcher.
You start this level on the river bank. Use your grenades to destroy the river boats. You will have to time it so that you throw the grenade into the water and then allow a few seconds for the boat to sail over it. As you walk towards the bridge, there will be a rocket launcher geezer firing off endless reams of rockets in your direction. Get close and then counter attack after dodging each missile. Once safely over the footbridge, you will come to an enemy encampment. First, shoot the soldier next to the water tank, and then turn to take out the pillbox. Now stand a safe distance away from the watch tower and then wait as the enemy soldiers start walking towards you. With any luck the grenades lobbed from the tower by their mates should take them all out efficiently. Now, simply blast the tower. Around the next bend will be a boat loaded with enemy troops and several foot soldiers, all of which can be easily disposed.
Things are heating up. First there is an ambush by concealed troops, then you have got a watch tower to contend with. Once you crossed over the bridge, take out the boat full of troops and then do untold amounts of damage to the enemy encampment just around the corner. There will be a rocket launcher bloke, if you get into trouble whilst tackling him, seek refuge behind the pillbox and then attack blast him at regular intervals. Once the camp has been destroyed, dash over the bridge and kill the remaining few soldiers to complete this level.
As we near the end of the jungle territory, the natives are restless. As a result of your extremely loud gunfire disturbing their strange gods, they have decided to come out and fight in their droves. This level starts in a familiar fashion with foot soldiers ambushing you from all angles. When you reach the natives, keep on the move to avoid spears and poisonous darts, you will find them extremely hard to kill because they are constantly on the move. When you meet the natives, each and every statue from then on will possess demonic qualities, and thus try to steal your worthless soul. A couple of rockets or a succession of shots will exorcise them effectively. For extra kicks, why not torch a few native huts, it's great fun and hey, it serves them right for becoming involved.
The final jungle level starts out as any other, until you notice some mystic native dude scooped inside a cave. When you stumble into view, he will wave his mighty staff around and an army of native zombies will shoot up through the ground. Pick them off as they arrive and brace yourself for the grand finale. A bit peeved that all his henchman have been vaporized, the mystic witch doctor will then transform himself into a huge werewolf. Then, he will proceed to either get working with his club or fry you to dead with his stagnant breath. If you have any rockets left, he can be easily picked off from a distance. Otherwise, get very close, preferably behind his legs, then simply blast away with your guns. He will not be able to touch you at such proximity, leaving you safe to kill the hairy oaf.
General tips for conquering the canyon
Out of the jungle and out into the open as you wreak havoc through a picturesque canyon. Start the level as you mean to go on by pepping the foot soldiers with bullets. As you walk over the hill, grab the bazooka and reduce the watch tower to rubble. The next hazard is a tank that can easily destroyed provided you have save a couple of rockets, otherwise get close and avoid the gun turret. As you go through the tunnel, prepare yourself for two soldiers that drop down from the other side on a rope. Another tank will attempt to get you as you emerge from the tunnel so be more than ready to rock. Just around the next bend, you will come to a log resting across a ravine. Kill the rocket man and then wait on the log. In the distance you should see two oil drums with soldiers coming up behind them. Simply fire off two rockets at the barrels and let the explosions take care of 'em. Up around the next hill is an enemy encampment complete with tank and watch tower. Obviously the tank takes priority in the killing stakes, so get to work. Take the right side and then pick off the rocket man and the dangerous mortar launcher as you emerge the other side.
When you begin the level, pick off the two foot soldiers that come towards you and grab the flame-thrower behind them. Now use your new weapon to attack the mortar operator. As you progress through the level, you will come to a big ravine with paths stretching off both sides, take the left route and then grab the invincibility crate as it falls from the sky. This gives you the added strength to overcome the tank easily. Now grab the bazooka lying around at the entrance to the next section. As you go around the bend, beware of the cunningly disguised minefield. Kill the lone foot soldier and then use your bazooka to take out the opposing rocket man on the rope bridge. Walk up to his peppered corpse and wait. In the distance at the other end of the bridge, more soldiers should come into view. You have got the rockets, so do your stuff. As you walk to the end of the bridge, look skyward for the huge helicopter flying overhead. It will perform a fancy turn and then fire a couple of deadly missiles in your direction. Evasive action is vital, in other words, leg it!. Now simply dash to the end of the level taking out the remaining soldiers. Just before the exit, you will come across two grenade-lobbing scum bags on the railway, take them out with a grenade or your Uzi, either way they are a pushover.
This level is the ideal opportunity for a mass killing spree. There is nothing mush to overcome other than legions of foot soldiers so the key is to go slowly and pick each one off as they appear in the distance. Once you have bagged the first lot, grab the idle M-60 rifle and get shooting. At the top of the next hill is a rocket launcher. Use your heavy arsenal to take out the onslaught of enemy troops as they attack in full force over the next series of hills. Eventually you will come to another enemy encampment. Hit the tents first, followed by the truck, for the maximum effect and hopefully you will bag a few baddies in the explosions. The last hazard is a tank. It can easily be destroyed by using the same techniques as before. Get close and avoid his sights.
Before you can exit the canyon, there are several last obstacles that must be overcome. Firstly, take out the foot soldiers that hassle you at the start, followed by the devious rocket men. You should see an enemy encampment in the distance by now. Blast everything in sight and then turn your attentions to the pillboxes. The last hazard on this level is the vile scum that emerges from the hovering helicopter. Take out the first two rocket launcher men as you would normally. Then, when the big mean dude drops down, hide behind the pillboxes and observe his routine. You will find that the safest way to hit him is when he is mouthing off at you. Simply fire short controlled bursts whenever he is giving it some lip, and before you know it the stupid sod will collapse and die a horribly grizzly death.
