The demo is a very bad representation of the game, the game is more or less what you make it. our main game mode is evolution, heres what that means

full island of Sahrani, 400 Square miles filled with 20 citys or so, your base is loaded with assets any anything you think you should do. you more or less can do it is a combat simulator, in order to win evolution, you must capture all the citys. it takes a day or two to do this. once all the citys are captured you win, Assets DO NOT respawn, once you break it you have to fix it. wich isnt hard. its just tim consuming so you dont take things you cant bring back. your rank is saved and people come and go as they please through out a game

for example, Vehicles can be loaded with just about anything that will fit in them, put 2 much in and it's full i love filling up a stryker with my favourite things(as well as my squadies favourites) and heading to a city

Lazer Markers, bring a lazer marker and if you have a harrier overhead armed with guided bombs, you can laze a target for the harrier.

like 20 different choices in assault rifle/Light machine gun, plus an assortment of Frag grenades, Flares, Smoke, Ammunition, Javeline missile systems, Stinger AA, M136 re-usable AT, etc etc. all of witch may be used to your disposal

a GORGEOUS graphics engine, you cant appreciate the full engine untill you have the full island.

some vehicles include

Stryker, available top mounted weapons (M2 50 caliber machine gun, TOW, MK19 grenade launcher)

HMMWV(available top mounts, same as stryker, however the stryker has a more intuitive system for using these weapons HMMWV is more hands on)

5 Ton Truck(huge bastards that carry 15 people or so, available as service vehicles for repairing or transport vehicles)

AH-6 Littlebird, Littlebird armed with FFAR rockets and 2 mini guns

MH-6 littlebird, littlebird with side seats for transport

AH-1 Cobra, lots of cool toys on this one

UH-60 MG blackhawk, transport blackhawk armed with Mini guns (these ones do their job well)

UH-60 FFAR Blackhawk, Transport blackhawk armed with FFAR rockets used for transport and CAS

AV8B harriers. armed with AIM9's or GBU's

A10 Warthog, the main gun on this bird is AMAZING, i've flown her at night and come down on targets with a 2 second burst. there is soooo much led tossed in that 2 seconds, easy to kill a squad with one burst

all kinds of enemy vehicles etc etc.

alot of good TG guys are starting to migrate to ArmA, the 1st-MIP for one have started transitioning, i've seen many first MIP ArmA n00bs in the past few days switch is hooked =D i can already tell, and the more you play the more addictive it is.
