FreeCS
FreeCS is a free-software reimplementation of Counter-Strike 1.5.
FreeCS is a free-software reimplementation of Counter-Strike 1.5 running on the FTEQW engine. All it is, is a game-logic re-implementation in QuakeC, an architecture independent programming language. FreeCS is not a game-engine as it relies on FTEQW (released under the GPL V2). All this makes it possible to play FreeCS on virtually any platform! No DRM! No third-party accounts! Just download, play, contribute. The game-logic is written by me with help of twhl.info's wiki. It has since been incorporated into the Nuclide project, which re-implements more than just CS 1.5. -

Super Smash FLash 2
Super Smash Flash 2 is the most must-play battle game with 28 classic
SSF2 Fan Club: https://www.facebook.com/SuperSmashFlash2FC/ Play SSF2 Online: https://www.freegames66.com/fighting/super-smash-flash-2/ Nice news for those who love Super Smash Flash game, the upgraded version is better and better with an extra 3 playable characters to swell the ranks too (Marth, Zero Suit Samus and Chibi-Robo). Super Smash Flash 2's gameplay is very similar to the official Super Smash Bros. However, the most interesting feature of SSF2 is that character's health is measured by a damage percentage counter. It means a character is attacked, the damage will be accumulated, and percent value gets high. The controls of Super Smash Flash 2 are also different from the previous version. Make use of WASD keys to move Player while the arrow keys are used to control second player. The O and P keys still remain in P-1's possession, the P key for standard attacks, the I key for shield, and the 1 key for taunting. -
