From shmup guru Kenta Cho, L.A.2 is similar to John Conway's game of Life but, well, just the opposite. Instead of creating cellular automata, your job is to destroy them. Swarms of cells grow and multiply around the edges of the screen with the occasional enemy craft hidden amongst them. Maneuver around the screen charging your glider weapon and releasing it to destroy advancing cubes.

Yet another excellent free shmup from the inimitable Kenta Cho, Titanion (Windows) is a new take on the classic arcade game Galaga. Cho has seriously sped up the pace and intensity, but was considerate enough to leave the player a gift: the dreaded tractor beam is now in your hands.
