Ammo glitch: get chainsaw and hunting rifle (or some other powerful gun) and start using the chainsaw. press spacebar and wait for 10 secs, still using chainsaw. then press space 2-3 times and the hunting rifle will have 99 ammo.
Glitch: If you are fighting the last man in a fight against anyone, and the 5% chance on a "Charming" weapon takes effect, you automatically win, because the "Charm"ed person is temporarily part of your army.
Needs a pause button. I missed about 12 phone calls because I couldn't pause this game. The link could stand to go, too. Almost died several times because I clicked the link instead of shooting the clones.
1st and 2nd levels are perfect for ground-taken and morale victories.
get 3 squads of infantry in the trench in 1st level, wait till victory, then go for ground on 2nd level
A super-good way of getting loads of experience: Upgrade hobbits to max and do battle # 4. hold "a" and switch to another tab/window, still holding "A". let go of "A" and go back to the game. the arrows should be autofiring now. just aim and repeat. any enemies who get past your barrage will get clobbered by hobbits.
