12 - Blowtorch & Corkscrew
*NOTE: I know you have the flamethrower for this level, but it's really only used for clearing bunkers and assaulting the first MG nest, use the big gun for all the rest.*
Move up and it may interest you to know you have a Browning M1919, a big gun, so I suggest you use that. When the checkpoint hits you need to go to the cover on the right as enemies pop up all around. Kill the ones to the left, then fall back to where your guys are taking cover and from here pop all the enemies you see. Move up the left side near the holes and there is a rock that provides cover for both. From here pick off all the enemies you see, and when most are gone up up to stop the stream. More enemies up the hill, so pick off and advance until the checkpoint hits and the MG turret begins to fire. Your best move is to toss one frag up the hill, move up while picking off enemies, then toss another toward the turret, move up, and then toss a final one up to the right of the turret's location. When you move into the turret's area, just use the flamethrower and burn anything that looks Japanese.
Through the tunnels watch out for the few enemies on the other side by a tiny pond. The checkpoint hits and you'll notice the boxes to the right have golden satchels on them. You can come here for more if you run out. When you move up I suggest huggin the small trench as you move to the right to flank the bunker's position. Just stay smart and when all the infantry are down, approach the bunker, burn em out, get by the opening on the right side, toss in the satchel (just like you call and airstrike), stand back, and fire.
*DEATH CARD 10: To the southwest of the first bunker, by the wall is the card.*
Assaulting the next bunker is very hard because of the grenade war that you must first survive. The second bunker is adjacent to the first, but you must go around a barrier and up to reach it. This is tough because there are a ton of enemies up there and they have a lot of frags, and yes, they always know where you are. You can try to kill the few to the left down below, but you need to keep the first bunker's battle zone open for you to retreat to when the frags are falling. An alternative is to just run up that path on the right and try and take out the enemies, but it's best to endure the grenades and then go up. Do the satchel again, along with the burning of the bunker first, and pick up more by the supplies nearby.
I say wait a bit and let your team move up. The reason is that for some reason when I went back to retrace my steps and then moved up to where my men were, the enemies were kinda stopped and allowed me all the time I wanted to shoot all them along the ridge. Otherwise just run to the abandoned bunker in the corner, but don't cross the bridge and pick off the enemies from here.
When you do cross the bridge two will rush you, then two will try to take up a position nearby, so take them out. The third bunker is ahead of this bridge along the right rock wall, but you need to kill all the Tojo on the field first when you approach this bunker, so fall back and pick them off. To take out the bunker just get to the right side of the opening and don't even flame it, just toss in the bomb, stand back, and fire.
Go up to the next area where you follow your tank and men up a hill. The left side is the tough side, so to right and aim for the top and toss a smoke up there, you should have 4 from the supplies. You can toss another deeper to the side as enemies will just keep coming, but also watch for the few to the left of this path in the grass. Run up to stop the flow with probably the flame gun, just watch out for the few inside the little rock structure.
Once inside and your men catch up, move up as you keep an eye out for enemies up high. Have your flame gun in hand because up ahead three banzais pop out of holes. The tricky part is that around the corner to the left is an enemy bunker and a sizable flow of enemies that cover it. One option is to gun in out, return fire and frags, and then run up with the flames. The second option is to toss smoke and run up there with flames, but you have to be aware of the enemies inside the bunker and above it. Once you clear all the enemies above it and around, your guys will move inside.
*NOTE: Keep an eye out for a Type 99 if you are low on your M1919, or just grab anything to replace it by this point.*
Enter and then run in with flames'a firin'. Clear out the first room of enemies and just a few in the second room. Move down the left path and there may be one more by the ladder. Go up after your team and quickly clear out the side of the room with enemies. Don't be shy about tossing frags here, then run out and sweep the room of fire to clear it.
Go up the next ladder but make sure there isn't someone at the top, and when you get up just stay by the ladder and the wall on the left and torch the two or three enemies waiting. Let your team get up before you do anything, and chances are from here you can ignore the grenade indicators. This part is all about luck and hopefully you have two smokes left. You'll use all your frags on the middle and middle back of this room. When you will go to the right by the boxes and toss two smokes, one to the back right and one to the middle. You'll sweep right firing a few bursts of fire, then go left and finish off all the remaining Japs. Finally, at the back you must go up the ladder and burn the four remaining enemies, and they are very generous to let you get up and kill them.
