Infantry

Your infantry is unlocked at 1 OS, and is the first rank in your army. They are great at destroying things that are close to them, but they can't do long range attacks, making them vulnerable to enemy defenses and cannons. But if you manage to get them up to the city center or something, that'll just destroy the structure. They also aren't pretty good at fighting defenses, so you should use your Archers instead. But when handled properly, they can be really helpful.

Here are the upgrades:

1 OS: Spearman

2 OS: Epic Spearman

3 OS: Soldier

5 OS: Medieval Soldier

7 OS: Phalanx

10 OS: Pikeman

20 OS: Hellburger

30 OS: Fusilier

50 OS: Shucker

75 OS: Aselter

100 OS: Eselar

150 OS: Expelter
