Maybe I just used that silly tse tse gun too much then, honest question what were the other options that constitute the widest range of options ever?
How about
- you disarm everyone
- you play in first person only
- you knock them all out and let them live either by tranquilizing them, using a fast combo or throwing them to the ground
- you hold them up and make them lie on the ground
- you go in like rambo and play like a third person shooter killing everyone
- you disable all the hud indicators, including aiming reticule, and see how much it changes the way you play
- you try to complete a mission without using a weapon, especially the destroy anti air craft mission
- you disable or enable reflex mode and see how much it affects the difficulty
- you jump in a tank and go loco
- you play as a ghost and don't interact with anyone
- you create a distraction that lures guards away
- you enter the base by going through the front door, side door, drainage system or hiding on a truck or by just blowing up the front gate by sticking c4 to a truck
- go for either paz or chico first, or get both at once
- you retrieve rather than kill the assassination targets
- call in the chopper at any time at various locations
- rescue all the prisoners, save none or simply kill them
- escape by vehicle, on foot or by chopper
and there's specific things you can do on each mission but you get the idea.
