BioWare has dated the Mass Effect 2 Firewalker DLC for 23rd March - or this Tuesday, if you don't like numbers.
The developer confirmed the date on Twitter moments ago.
This content will be free to Cerberus Network members and consist of a Hammerhead heavy assault vehicle, which you can use in five new missions. This vehicle hovers above the ground at over 120kph and has a guided missile system. Look: pictures.
Cerberus Network is the ME2 platform all players require to access the DLC. This is free to first-hand buyers but second-hand purchasers will need to shell out around £10 to download it on PC or Xbox Live.
