Panzer Attack and Two Roads don't have tips. I'll help!
Two Roads: While in the sniper scene, take cover, as one shot on any mode will kill you. At the end, use the sniper to pick off enemies from a distance.
Panzer Attack: Just because an area looks clear doesn't mean it is. After blowing up a tank, search everywhere for hostiles so you can truly clear up the area. The third area in particular has enemies hiding all over the place.
You're welcome! Oh, don't forget to mention the Rhine Forest glitch:
Rhine Forest features a glitch/easter egg. Near the cabin, crouching and walking towards the map boundary will cause the player to go into the hill. Anyone who does this is 100% untouchable unless they stand up, exposing their head. There's a snowman inside that area, meaning it was possible that this "glitch" was intentional.
i would like to add to multi on rhine forest. on the second floor of the cottage house thing, therres a corner with a hole throug the floor. if some one comes up, fall throug the floor and back up the stais and kill em. works 99.9% of the time.
