Rising Storm/Red Orchestra 2 is on sale for 4.99 this weekend. Free weekend as well. It's a good WW2 realistic shooter with a fair learning curve. Another B12er and I play it right now, so join up!
They were giving it away for free a couple of days ago
I've been playing this a bit. It is a fun shooter. Combat is very deadly with you scrambling to cover just in front of you hoping you don't get shot. Team play is important with players having to support each other to assault positions.
Recognising friends from foes is difficult. The uniforms and run animations are different (Germans wear dark green, run with rifle in one hand. Soviets wear beige/yellow green, hold rifle in two hands when running) so expect team killings, especially if you run towards friends in a heavy combat zone.
The games rather demanding on PC requirements. I've found turning off Depth of Field, Bloom, Motion Blur and all those to help vastly in stability, but the new maps with Rising Storm (The Americans vs Japan maps) are much more cluttered with trees and objects than the original Axis vs Soviets maps. I can run the game using a Intel i5, Radeon HD 6870, 4gb ram, ASUS P8P67 PRO motherboard with graphics around medium/high. Partly I think the games rather badly optimised, it's not really really detailed but there is a lot of things going on with an engine designed for deathmatch, small maps (Unreal 3).
The give away was/is a free version of Red Orchestra 2 without Rising Storm. You can play the Rising Storm maps but only as a Rifleman and you can't get experience (This gives you small upgrades to weapons and different class looks). I haven't played the Rising Storm maps much due to them not loading before I get kicked back to main menu. Probably due to their intensity of foliage/shadows.
