The MCS vehicle menu on FiveM with the full roster of aircraft and armour open to spawn

A War Thunder alternative without the grind

War Thunder is free. So is this. The difference is that the F-22 takes sixty seconds here, not six hundred hours.

What you get on MCS

  • Every airframe from the first connection: F-22A, Su-57, F-35, J-20, F-14, MiG-29, Typhoon, Rafale, Gripen, plus attack helicopters and armour.

  • A flight model built for the merge, not for the checklist. Keyboard or pad, missiles that behave, energy that matters.

  • Lobbies that fill: public team deathmatch and free for all, a 1v1 dogfight arena, ranked from 1v1 to squads, private lobbies with a code.

  • Real people in every fight, and two evening flight windows a day being set up so that a full server has an hour you can plan around.

What you should know first

  • It runs inside GTA V through FiveM, so you need a copy of GTA V on PC. There is no console version.

  • The physics are GTA physics tuned for fun. Nobody here models a compressor stall, and that is the point.

  • There is no progression to chase. Ranks and leaderboards exist, but the aircraft do not care about them.

  • The first load takes three to five minutes because ninety three custom vehicles come down with it. After that, seconds.

War Thunder is a trademark of Gaijin Entertainment. MCS is an independent FiveM server with no connection to it, and the comparison above is our own honest reading.
