came cross TOW2 demo last night, downloaded and played! what a jaw dropping! i loved it. I struggled however and couldn't pick up weapons off dead bodies! It asked me to pick up a weapon by a burning truck to blow up a tank but i couldn't pick it up! i struggled with making the solider maintain his position after he reached his destination but he wouldn't stop, he would continue moving toward the tank and end up dead!!
