New weapons
Grey Matter has fleshed out the Soviet and German arsenals somewhat. Each now has a semi-automatic carbine rifle, the Germans get the Gewehr 43 and the Soviets the SVD 40. These rifles are more in line with the M1 Carbine than the M1 Garand in terms of damage, but closer to the Garand when it comes to accuracy and rate of fire. Each rifle holds up to 10 rounds and, unlike the Garand, can be reloaded any time.
In addition, the US, Soviet and German forces get deployable light machine guns. The Browning .30cal is of course the American weapon, Germany enjoys the legendary MG34 and the Soviets have the DP28. The deployable LMGs work by hitting the right mouse button (or whatever works as "aim down sight" in your config) to deploy, and then the machine gun can be fired. All three have very limited traverse but insane rates of fire and very high accuracy for automatic weapons. It's unlikely they'll see their full potential unless used by a dedicated clan, but they are quite devastating.
Finally, there are new weapon pickups, the satchel charge and two new anti-tank weapons. Satchels are super-grenades. They're great at clearing out buildings, do a whack of damage to tanks, but should be conserved rather than spammed out like grenades. Their utility and the fact that they're a pickup item makes their use more discriminate.
All grenades, including smoke grenades, as well as the satchel can now be cooked off. Simply select, hold down the left mouse button and hit the right mouse button to start cooking. Then release when you're ready. The cook-off time for satchels is a bit longer, while grenades take approximately as long to fire off as in Counter-Strike, perhaps a touch longer. With skill, it's almost too easy to clear out a room, and if you've got someone chasing you around tight corner just drop a nade with 2 seconds left on the timer to give him a nasty surprise.
The last of the new infantry weapons are the Panzerschreck and Bazooka. They appear to have the same damage as the Panzerfaust but with better accuracy. Like the Panzerfaust, they are pickup items and also best used from crouching or prone positions. So now we've got all these anti-tank weapons, but what tanks are in the game?
