Resistance: Fall of Man
The M5A2 Carbine is Nathan Hale's starting weapon, and is also the default weapon for the US Army and British Armed forces. It is exceedingly sturdy and will more often than not be the last line of defence against the Chimera.
The Carbine is a good multi-purpose weapon, but it is very effective against Hybrids and Slipskulls. Aim for their head's and they won't cause much of a problem for too long.
The grenade launcher extension is also extremely useful against the bigger enemies, such as the Steelhead, which can be taken down in one hit, but ammunition for this is usually very sparce, so make sure it isn't wasted when obtained.
Tip: Unlike online mode, the enemies (particularly Hybrids) won't dart around everywhere. Make sure you use the scope to line up some nice headshots before they get too close to do some serious damage.
M5A2 Carbine Online
The M5A2 Carbine is the starting weapon for the Human forces. It has the 3rd largest clip size and has the 2nd largest ammo pool. In terms of damage, it is the 2nd weakest, but its fast fire rate, makes it a formidible weapon, especially if headshots are made. For example, the M5A2 Carbine can kill someone in approx 0.88 seconds if constant headshots are registered.
The secondary fire is exceedingly powerful and in some cases, could be considered the best weapon in the game. When carrying two grenades in the Grenade Launcher, the odds are heavily in the players' favour.
Tip: The Carbine has good accuracy, even at long range, but if you're attacking someone from behind try to get closer before launching an attack. They'll never know what hit them!
The M5A2 Carbine returns in Resistance 2, although it has been slightly tamed this time around. It isn't as accurate as it used to be without aiming, and it isn't as powerful either.
However, it is still very useful against generic Hybrids and other Chimera and there is usually plenty of ammo spaced around levels. Again, aiming for the head is a surefire way to bring down Hybrids quickly, and Steelheads.
The Grenade Launcher expansion is still present in Resistance 2, although it now takes longer to reload and the blast radius isn't anywhere near as big. However, if it hits dead on, it will kill most enemies instantly.
Taking The M5A2 Online In Resistance 2
Cooperative: Only the Medic class can use the M5A2 Carbine in the Cooperative Mode and it's the first weapon that they can unlock. It's probably more effective to use the XR-42 Phoenix though, unless you want to use the Grenade Launcher.
Competitive: With the new ability to pre-select a weapon in Competitive, the M5A2 Carbine has become more of a specialist's weapon. It's a good all-round weapon, and provides an adequate solution to both close-range and long-range combat. The Grenade Launcher also allows for quick and easy kills.
