PC gamers alive in the 1990's will remember the XCOM series of games as bastions of the strategy genre. In each, you took control of a global organization that was tasked with defending the Earth from aliens; you did so in turn-based missions, where you killed enemies, escorted VIPs, and defended objectives.
Now imagine that (with some tweaks, of course) on Android.
The premise of The Hunters: Episode One is relatively simple: you are the leader of a team of mercenaries, and you can take different contracts on a daily basis. Completing these contracts nets you money, which can be spent upgrading your mercs with equipment and armor.
