Actually, I played lots of Outtrigger and I was actually pretty good, online, with it.
The main thing I found out, you could take advantage of, was the super quick way you switched weapons(and the fact you can have ordinance out there while firing another weapon). The game was made, more so than other FPS of its time, for multi-ordinance combat. I typically pressed the weapon-switching button faster than the trigger button.
I always had one rapid firing weapon(which was my secondary tactic, the other two being primary), one grenade style weapon, and one explosive weapon. That was my style. And I got loads of wins by playing this game like I would, get this, Virtual On.
Most FPS games have you grab a favorite weapon of yours and then you throw down. But if anybody is a Virtual On fan, they know that game specifically made you play Multi-ordinance tactics, in fighting game fashion.
For instance, anybody remember the Guile zoning tactics of his slow Sonic Boom, and working it into supressing the enemy so you have tactical advantage? Just like playing Temjin and Using the Bombs (Right trigger weapon) to either zone your enemy into a location for your next attack as the explosion expands. (or to create a safe zone that ate laser shots for you to press your attack with advantage ala. Guile?) Also equivalent to using the grenade (or mine) weapon as a zone tactic for your heavy hitting direct-fire weapons.
Because you can have multiple active weaponry going at the same time, and the generally close-quarter arenas, the game was pure bred for VO tactics. Normally, in another game, you either can't do that, or there's too much time between switching weapons, to do that.
I want to play this online now with any who would have it, but I understand Seganet is no more, thus I guess it's the damned split screened deal with three others when I do get the chance to play it. ---The control scheme for OUTTRIGGER was a bit fucked though.
