Sierra Online’s Red Baron Arcade will be released on the PlayStation Network on the 18th of September.

Red Baron Arcade is an arcade air combat game featuring online multiplayer capabilities. Set in WWI, the game sees players manning the gun turrets on an aircraft as they take on pilots in dogfights and seek to rise through the ranks of the Red Baron’s squadron.

Battle AI or pit yourself against up to seven players online in Deathmatch, Team-Deathmatch and Capture the Flag modes.

A free demo of Red Baron Squadron will be released on the PlayStation Network on the 18th of September. Download the demo and jump into the multiplayer action with up to eight players online in a special battle arena available in the game – a PlayStation Network first.

Assault Heroes 2 is this week’s XBLA offering. Developed by Sierra Online, it will be available from tomorrow for 800 Microsoft Points.

Assault Heroes 2 reveals that the enemy in Assault Heroes is a sinister force’s pawn. Armed with stronger weapons (including the new sub-zero freezing ice cannon, homing missiles, rocket launcher and upgraded firearms) and vehicles as well as the ability to hi-jack more powerful enemy units (including attack helicopters, armored tanks and mechanical walkers), players must now find it and destroy it.

The game features on-foot game play where players must use more firepower and take advantage of the new dodge roll feature to survive being outside their vehicle.

Face persistent enemies and bosses both on land and in space, through the Snowy Mountains, Rainforest and Outer Space with destructible terrain. Fight alone or battle with a friend using the enhanced two-player cooperative mode.

Sierra Online has announced that the award winning card game Lost Cities will be available exclusively on the Xbox 360 this Spring.

Lost Cities sees players drawing from a pool of cards as they attempt to amass the most points and make prosperous expeditions through various lost cities. Prepare to venture through the Himalayas, the rain forest in Brazil, the desert, volcanoes and the ocean.

Lost Cities has been priced at 800 Microsoft Points.
