Known Bugs
1. Your mercenaries sometimes get placed partially in or off the ground when entering a zone after being ambushed. Make sure you save often.
2. Sometimes the enemy who ambushes you gets placed in the sky. They kill you fast but you cannot kill them. Make sure you save often.
3. When running, it is possible to get trapped in the middle of an object. It has happened many times with my hummer. Make sure you save often.
4. After completing a mission and while claiming the payment it will say something like "You are in danger!" instead of "Mission Complete." and will continue with the payment.
5. The entire game will crash when running some versions of Yahoo Chat.
6. When giving the order to climb a ladder during battle, your mercenary climbs a different one. (Only tested during a battle in San-Miguel - The Residence.)
