Hoolio, it's nice that you know a lot about the Germans during World War 2, but c'mon, this is a game. Calm down about "hating people who think the enemy soldiers are nazis"
FOR PEOPLE THAT GOT STUCK ON WAVE 101: TAUNT. that's all you have to do to get to the next wave. However, there will be a lot of waves later on that has a similar problem. Just keep taunting. oh, and to the makers of this game, get some women in here, can't be a sausage fest ya know.
1. Get an engineer ASAP because he's gonna be real useful. 2. Dig 1 or 2 trenches and put your starting troops in there. put 3 sandbags in there too if you want, however i don't know if it provides more protection. 3. wait till you get enough TPs and build a bunker. This bunker will be your fallback point because it's invincible to Tank rounds and grenades. 4. At this point you should be doing just fine with your 5 soldiers. No arty/planes will fire on your position. If want, you can get a spec-ops to help out your troops. Or you can just replenish your starting troops. Either way works fine. When you're ready, get a gunner and put him in that bunker. Keep in mind that no matter what, do NOT go past the limit of 6 soldiers. IF you do, planes and artillery rounds will be fired upon your position. Now, all you need to do is keep buying the ranger training thing for your gunner until he's over 50 in his GUN skill or whatever.
Here's how you kill santa: 1. Get a lot of troops with Grenades and wait for santa to come on the battlfield. Now as we all know, no one's gonna shoot santa because he's freaking santa so yeah, you gotta hit him by accident. The best way to do this is to have troops lined up in a horizontal line and taunt the germans. Occasionally a german or one of your troops will throw a lucky nade that blows up santa :P 2.Get a RADIOMAN and call for either Close air support, arty strike or bomb drop. Arty strikes and bomb drops will work best when Santa's at the TOP half of the screen. 3. The last way is to have tanks. This will work BEST when you get to wave 100+ because enemy tanks as well as your own will be shooting like there's no tomorrow and you'll kill santa eventually.
Everybody listen up. Get a bunker and a gunner and that's basically all you need to own every single german that comes onto the battlefield. get the Gunner inside the bunker and keep buying the Ranger Training thing for him until you think it's enough. After you're done, watch that gunner mow down anyone that spawns.
@ Liquid Heroin: It's not confirmed to be in Vietnam for the next game. Where ever you got that it's wrong. There was a TIP in the game saying "the Next Mud and Blood setting will take place in the Medieval Times.
