Finally, an advertisement appeared on XBLA last night announcing Gears of War 3 to release in April 2011, seems to be an early slip on Microsoft’s part as the advert has now been removed.
IGN also have speculated the following about the new gamely features through a trusted source of theirs:
According to the source, Gears of War 3 will include all-new Locust enemies the feature "tentacle-like appendages" that can extend to cover spots. To combat this, Delta Squad COG members will now carry explosives that can travel underground and take out enemy positions.
Gears of War 3 will also have "a heavy duty mech suit" that COG members can use for both protection and causing havoc on the battlefield.
These new combat mechanics will be used in both singleplayer and multiplayer, according to Edge.
Gears of War 3 will be set during the summer, and include a host of new locations as well. The biggest addition are new underwater levels. [source]
Apparently a trailer for Gears of War 3 will be released this Monday, but remember all we are 100% certain of is this: Gears of War 3 is confirmed.
Get your chainsaws ready. 😀
