Four new international character posters from Battleship have gone online. The movie looks pretty ridiculous, and at this point all I’m hoping for is a good time watching water robots fight battleships. These new character posters highlight Liam Neeson, Rihanna, and Alexander Skarsgard (we saw the Taylor Kitsch one last week), as well as one of the aliens that's sure to wreak havoc on said actors. I'm assuming the alien isn't Darth Maul dressed up as Master Chief, but this character poster begs to differ. It’ll be interesting to see if we get a look at the creatures outside their spacesuits (Oxygen is apparently an alien invader's worst enemy), but for now we’ll have to settle for suited-up extraterrestrials.Hit the jump to check out the posters. Battleship opens May 18th.

Here’s the synopsis for Battleship:

Peter Berg (Hancock) produces and directs Battleship, an epic-scaled action-adventure that unfolds across the seas, in the skies and over land as our planet fights for survival against a superior force. Inspired by Hasbro’s classic naval combat game, Battleship stars Taylor Kitsch as Lt. Alex Hopper, a Naval officer assigned to the USS John Paul Jones; Brooklyn Decker as Sam Shane, a physical therapist and Hopper’s fiancée; Alexander Skarsgård as Hopper’s older brother, Stone, Commanding Officer of the USS Sampson; Rihanna as Petty Officer Raikes, Hopper’s crewmate and a weapons specialist on the USS John Paul Jones; and international superstar Liam Neeson as Hopper and Stone’s superior (and Sam’s father), Admiral Shane.

Berg directs this epic action-adventure also produced by Scott Stuber (Couples Retreat), Sarah Aubrey (The Kingdom), Brian Goldner and Bennett Schneir of Hasbro (the Transformers franchise), along with Duncan Henderson (Master and Commander) and Jeffrey Silver (300). The film is written by Jon Hoeber & Erich Hoeber (Red).

The battle for Earth begins at sea.
